Quote - Um I'm not talking about MY uploads, I am talking about having troubles with downloading OTHER's freebie stuff. It's their files that are coming up corrupted in my program files.

I have no issues, like you mention.
If you have a new PC & the old one is fine...what has changed?! Do you have some malware sniffer or antivirus that could be checking/corrupting any downloaded data. Also is it only data from Renderosity that you have an issue with or from any site ?!

This should help to start finding the root cause at least.

BTW:
I can relate to Slavs comment as your 1st post reads "anyone else have troubles with uploading freebie objects for different software products".
I assume you meant downloading :)
