I'd say when you have custom careers, you should be wary of how they'd work with
any other hack. There's some that tend to cause trouble, while others go on without too much of a fuss...

The
47f6694823b08ee078ac6d52158e192b_0001.package and
47f6694823b08ee078ac6d52158e192b_0002.package files look a bit questionable to me... sort of like they're duplicates of each other, only the difference between them is the very last number. Are they the actual career files that you downloaded? Try pulling those two out and running your game without them to see what they are. That way, you've already gotten rid of the vast majority of the errors.
As for the InTeen part... can't really help you much here sadly.
(Insim = not InTeen... so no support for it on this site) I know that there's a lot of careers that are not friendly with it, so try to find some info by looking through the manual/reading through a few tech support threads on the InTeen site. I'm sure you can find a solution there better than you would here. :angel:
