I chatted with Pescado about this in grah. The objects are not showing up for people who have not installed the EA downloader because it creates a sort of Stuff Pack for them. To use the files without the downloader, they must be converted to a base-game code. It's easy: load the file into SimPE, open the OBJD, and edit field "0x0040" to say 0x1 instead of 0x1000. Commit for each OBJD and save.
I'll upload the fixed objects once I have all of them done, and anyone who wants to can distribute them again.
So that was the problem with the sollution for the previous objects... But I didn't understand a word of it because I'm clearly not as good with computers as BastDawn and other hero's on this forum. Does anyone have a clue? Thanks a whole lot!
