Iheartcats: I recently was playing Baldurs Gate 2 and was going through the storyline when I found that traveling to the gate district from the game screen map caused the game to minimize, and finally hang (essentially a crash) since I had to close it. I tried different save files but the problem persisted on each.

So I thought it might be a file corruption problem so I downloaded and the BG2 game again from GOG but this time I had the setup file check the integrity of the download. Before it finished it gave me this error message (see picture)

I'm running the following:
Windows 7 64 Bit and I have the required system specs to run the game. My video drivers are up to date as well and I just ran through Planescape torment without any problems. I've allowed administrator rights to access the BG2 files as well.

So besides re-downloading the files yet again can anyone help me with this problem if it's on GOG's end?

Hickory: There is no other option. The integrity check has failed, which means the installation files are compromised. You must re-download them again, but before you do make sure you have cleared your browser cache or use the GOG downloader, and delete all previously downloaded files first.

DeMignon: You'll find plenty on these topics in the Internet.
