I'll answer here and your PM. I use Opera, version 12 and 22, and have no problem. My Firefox did give me a blank screen, but in the upper left corner it stated "Update browser". I only have that on my system for a once in a great while when a site refuses Opera.
Upgraded my Firefox to ver 30 and goes right to it.
IE (UGH!!!) 32 and 64 bit both work OK.
See if you have a friend who will try it for you.
I'll ask the Admin who knows how to do things with it. He built it for me and my fellow SMR buddies and made me an Admin, but unless I really need to know how to do it, I don't bother. Ripping this game a new one constantly is enough for me.
As to 2K and their knowledge of what we have done - I sent them Emails about a subroutine to load SAM maps. My third, and last, Email was 4/16/14 and I have not heard a word from them.

The things they could do with the stuff we have done with the game they own..........

I'm correct 97% of the time..... who cares about the other 4%....
