Yep, I am not getting error messages but when I save the model, it stays on the screen after saving and the only way out is to exit the program and restart. It saves the model, but it doesn't go back to the main menu. The same thing happens when I try to repack characters (although some do work??), ie I don't get the screen that asks if you want to upload.
To create models I use PPP, then tweak then 'til my eyeballs fall out
I suspect the problem has something to do with Windows 7 and the program files directories. It really doesn't like anything saving into them. I have full admin privileges and I run the program as admin. I've also made the relevant directories attribute free (ie no read only rubbish)
