Hi Guys,
Ive read a few of the posts regarding this topic and disabled firewall and run as administrator etc but still cannot get the file integrity checker to complete. Parts 1 and 3 I have now downloaded 4 times (takes 2 hrs on my connection each time) and all with the same results.... I do not want to do the GOG downloader as it will take over 8hrs and possibly have the same issue?
File sizes match the other users on the forum.... Advice?

Ok so I found where the GOG downloader saves its files and put files 2-4 into the folder and download number 1s chunks to check. It actually worked now and constructed a valid file for part 1, now Im going the same for part 3... I would highly recommend that GOG checks out files 1 and 3 from the direct download as they more than certainly are damaged... My router logged no packet loss or data errors during the 4 occasions I downloaded part 1+3....

Edit: Also the reason I don't like the GOG downloader is because it has no speed limiter, which renders the internet completely useless to other people on my network! Hope that feature gets added soon or perhaps I am too blind to see it?

Edit2: Having quite a bit of trouble with file 3, keeps giving the error "There has been a problem, please contact GOG support" or something similar, will update when I have the correct error
