Gambit runs no problem when whenever I go to save I get an out of disk space error, I have 100gb free though...

Any idea what is causing this? Is it a liscencing problem?

the reason for this is gambit starts in drive c: and when it tries to save there it gives this error, next time go to console and start that in some dir say c:\gambit, so after working try to save in that dir not in c: ...it shall work

Not sure I follow, how can I start gambit in a directory?

I've just been running from F:\fluent.inc\ntbin\ntx86\gambit.exe

it doesn't matter you start gambit .. you should save the files in some folder like c:\gambit etc, if you are saving in c: then there is this problem .....

That fixed it. Many thanks!
