Re: I can't upload to the exchange
@jaimeroo11 Among the possible issues is that you've hit your limit of uploaded content, which is something like 2 GB total.
If that's not the problem, try uploading something in a clean user folder. Move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop, open the launcher to create a new folder, then copy one file from Exports in the old Sims 3 folder to Exports inside the new folder. You should be able to at least try to upload the item; let me know whether it works.
