Forum:Old Willowtree version issues

Hey guys, while I'm waiting for the scaling patch on the 360, I decided to reinstall my PC copy of Borderlands and leave it at 1.00 so that way I could create insane weapons and gear in Willowtree. Just to screw around for a bit, have some fun. I've noticed that the new Willowtree versions do not go well with the stock game, so I decided to use one of the earlier versions of Willowtree. The only problem is, my antivirus software seems to think there's a virus embedded in Willowtree program I've had since it came out! What's worse, every copy I've tried to download has the same problem. So, I just wanted to ask, does anyone know if the old versions of Willowtree are all corrupted, or is it just my anti-virus software being anal? Thanks.
