I think I've downloaded the game 3 times now from GoG.com and each time it's telling me the downloads are corrupt. I'm using the program to check file integrity (which takes AGES) and every time I do, it finds that almost all the files (2-1, 2-2, 2-3, 2-4 and 2-5) are always corrupt.
I can't use the download tool either. This morning it wouldn't let me download the game since it just had an error and now it won't let me log in at all.

So how do I fix this? I've paid for the game and can't even play it.

Never again am I using this service.
I'm very dissapointed.

I really wish I had went with Steam. Extra £3 but well worth it when you can actually play the game without having to search the internet for hours just for solutions to the problems with this particular service.

Got the game downloaded through the downloader at last.
Now it won't install. I click on "install" and it does absolutely nothing.

I really want a refund already. This is just abysmal.

You should be posting this in the game forum.

In any case, go to the donwloader folder and double click the .exe.

If for some reason it still doens't work start a thread on the game specific forum.
