I did a fresh install of Baldur's Gate Enhanced Edition, and after going through all the trouble to create my party I get a message saying there isn't enough room on the disk (this is absolutely not true!)

If I venture forth and save my game, it's not there - I lose everything. Anybody know how to fix this? I'm on Windows 10 64 bit.

Baldur's Gate II run's perfectly. This is the only game in my GoG library that won't run properly.

the issue is prob the location of the folder your save games are in

where is the save game stored? i,e, on my system its D:\Docs\Baldur's Gate II - Enhanced Edition\save

if you have your in C:\program files or worse "onedrive" then that is the cause of your error
