dude - please read the first post in this thread and read the section on RAR files and what you are supposed to do with them

um

those are the names of the RAR files...

Download the RAR from the first post in this thread: http://www.insimenator.org/showthread.php?t=2793

ok - by the numbers - delete the contents of your thumbnails folder :

My Documents\EA Games\The Sims 2\Thumbnails

delete this file Groups.cache

from:

My Documents\EA Games\The Sims 2

move the entire contents of your SavedSims folder to a new location outside MyDocuments

restart the game - create a new family - look for the merman as a fullbody in the clothing categories of Adult.

Ahaggard: if you have nothing in your Downloads folder but MESH_ju-beos_merman.package and one recolour, then it should show up in the game as a fullbody clothing for all categories.  If not, then there is something seriously out of whack with your install.

I will try it it. I want to get rid of the faulty file anyway because that is not the only problem i have had.

Ahaggard,

If you feel patient and motivated enough, there's a way to find if the issue is a conflicting file (which is likely), and then which one it could be.

First, move all your downloads (except the merman files) in a new folder on your desktop, then launch the game: if the merman shows up, then it's certain that it conflicts with another file.
So now you have to find out which it is, and this is the long and boring part.
Put back half of the files into your downloads folder, launch the game - if the merman shows up, the conflicting file is somewhere among those you left out, if not you just put in back in your downloads.
In the first case, add back one half of the files you removed, in the other case remove one half of those you put back in, lauch the game again - and proceed like this until you narrow your research to the faulty file.
I'm afraid there's no more convenient way, and I'd understand if you weren't too eager to try this...

Here is the manual of S2PCI: http://sims2pack.modthesims2.com/index.php?page=4

The red things are hacks, I haven't heard of a hack conflicting with the meshes before, but it's possible I guess.

Not necessarily - try checking your downloads folder with Sims2Pack Clean Installer - look for empty packages and duplicates first.

In many instances, if you have more than 8000 downloads the game starts to get buggy, there is no clear indication which thing may be causing the conflict, if could be a refrigerator recolour for instance or another object or skin mesh.

As more people make new things this is increasingly a risk.  Maxis has not devised a fool-proof method of avoiding conflicts.  I have even had hurt and woe come on me from Maxis official add-ins (especially the Christmas items, the Alienware computer, and the Urbz game).

It may take some time to find what is causing the conflict; and the solutions are very limited.  One is delete the offending item, the other is more technical and involves doing some mumbo-jumbo with SimPE.

I would prefer to limit the search to the offending item for the moment, as it would be beneficial to know what is causing the conflict so future downloaders will know what they have to choose between.

hrm - do you by chance have the Christmas content pack installed?

It sounds like you have a mesh conflict at this point.

Could you give me more information?  What EPs you have? did you place the files in the Downloads folder or a subfolder?  etc
