TheMysticalOne is doing a full set of the Maxis meshes with Warlokk's magnet sets applied to create all the Warlokk sizes.  You can find his stuff in Warlokk's Tower/Guest Add-ons.

Did you do all the steps I describe in this post?

Did you open the Neighborhood package or did you go through the Neighborhood Browser?  I think I heard that happens if you just open the Neighborhood package.

The Sims 2 is very touchy about registry changes, so it might be complaining about something missing that doesn't even belong to it.

Moral of the story: Backup the registry with regedit before uninstalling anything!

Is it just the CPU meshes?  There is an EP5 version of the maternity wear hack available now...

Yes.  Delete the N001 folder in your current install and paste the whole thing in from your backup.

When you pasted your folder over the Maxis one, it sort of "merged" the two, which will always give you bad results!

Your first post links to the athlete board short mesh but says body builder in the text!  Please clarify?

To put your clothes in subfolders you have to have NL.  Other downloads can go in subfolders with just the base game and Uni.

A. Unzip or unrar the file as necessary.  You should have either a Sims2Pack or a Package file.  
A1. Package file: Use Windows Explorer to open My Documents/EA Games/The Sims 2/ in another window.  If there's no Downloads folder, make one by Right Click in the folder window, New->Folder, then type "Downloads" without the quotes.  Open up the Downloads folder.  I like to make subfolders by creator; if you do this, open up that folder.  Now use the right mouse button to drag the package file to this folder.
A2. Sims2Pack file: Use either CleanInstaller or MultiSims2PackExtractor.
A2A. CleanInstaller:  Once the program has been installed, just double click on the Sims2Pack file and click Install.  
A2B. MultiSims2PackExtractor: Run the program and choose the folder where the Sims2Pack file is.  Click Go.  You'll now have a bunch of Package files.  Follow instructions for Package files.

B1: Already purchased beds: Go into Buy mode.  Click the swatch book.  
B2: Buying new beds: Go into Buy mode.  Choose a bed.  Kind of hover over the thumbnail for the bed.  
B3: Next: You'll see a popup with your installed choices for bedframe color and bedding.  The custom ones are to the left which is counter-intuitive, but then, this is EA/Maxis.  Click the one you want.  You should be able to click on a few to see which one you like best.  When you've got your selection, place it on the lot.

C: Repeat B and pick an ugly Maxis pattern.

Ok, what's with the white socks with the underwear?  Don't get it personally!

Thanks for reloading the meshes!

Lol, it's the attachment eating monster!  You might want to check the MTS2 link as well.  I didn't see the meshes there either.

themysticalone, thank you for doing all of these, especially the ones that needed meshes altered.  As an added benefit, they're currently coming up at the beginning of the list in BodyShop, so they're easy to find when making new projects.

If you're taking suggestions, I'd really appreciate the NL formal that flares out at the knees.

Thanks much!

Well, I must be suffering an embarassment of riches or something... but I'm not seeing the link for the mesh file!  Can you direct me?
