i have a better one. if it's the models.big crashing then you can do more troubleshooting. he's right, it's a huge file to upload.
if the models.big is crashing, there's two likely candidates: uniforms or cyberfaces. so take the models.big file from 2013 and open it in biggui. extract all of the cyberfaces in a separate folder and zip it up. use Tit to install those cyberfaces over the models.big that works. if it crashes, then we know the cyberfaces are doing it.
