Can't play entertainment Mode (Pandora Directive)

Hello there,

Just dowloaded Pandora from GOG, everything works fine except when I try to go with entertainment mode. I click OK and then nothing happens, the game is frozen. I can only move my mouse.

Then I restart the game, select adventure mode and it works!!! How is that possible? Have you ever heard about this issue? I guess I could simply run the adventure mode, check the hint and then I would automatically go back to entertainment mode right? (With easier puzzle and everything) Only problem is I won't get the 1,500 points lol and it's not like I remember everything in Pandora.

I am on a laptop using Win 8.1 and Nvidia.
