So people still use proxy. Hmm Okey. It might be that.
Problem is that all proxy handling is handled by windows. I do not handle it my self inside MC, I use existing functions in Windows for that.
I can't really fix it unless I can recreate it. So a video is to no use.
And since it can't talk to the net, It can't even send a crash reprot to my system. So I do not have that to go on.
I will add it to my list to check,
If you start the MultiUpdate , does it also crash if it checks for new version? it is using similar ways to talk to internet
