Larian Studios Forums Beyond Divinity (English) Technical Problems Protection system drivers... restart your computer

I don't think the Polish publisher ever released the 1.49 patch for the original disk version. You can try installing the 1.506 patch, but I do not know if it is compatible with the disk version of the game, or the Polish version.

You may be able to find a no-CD hack around somewhere.

The download version includes a number of compatibility fixes and higher / widescreen resolution support. It is available as part of the Divinity Anthology or separately from the Larian Vault, GOG, Steam, Gamersgate, etc.
