game wont go full screen...plus more issues..

im actually lost...you guys are pretty smart here....so when i play 2k I get two major problems when I play....number 1 I cant save an association...i get an error message and it wont allow me to save almost like i dont have enough hard drive space to save the game (which is not true i have tons of space)...it allows me to save rosters, settings, and myplayer stuff but not associations....also my second issue is i cant get the game to return to full screen....the minimize and maximize button is actually "greyed" out and isnt clickable....yeah some weird things are going on and I have no clue...i wonder if its a virus....

I used to experience the first error with the DVD-ROM version of the game, whenever I'd insert the disc and let the game auto-load. Whenever I did that, I was able to overwrite any existing save files, but I'd get a "not enough space" error whenever I tried to create a new save. Presumably, there's a bug that causes the game to try to save new files to the game disc, which obviously isn't possible. Exiting and launching the game from the desktop icon or Start Menu got everything working properly again.

Try pressing Alt-Enter to return to full screen mode.

alt enter does not work
