The Launcher gives this error so I followed the support link and followed the directions to verify the data. I did so three times on Steam. All three times, all files were verified as Good. I have been able to play as a Barbarian up to when I find and talk to Shadowheart in the shell before saving her (no further spoilers). From what I can tell from the support page, I should be crashing at game launch and not even able to play.
Normally I would delete the entire game and re-install BUT I have a fast computer, very fast internet and yet even though I downloaded the game within 15 minutes, maybe 10, it took an hour to write to my SSD drive. I want to play, not wait, 24 hours while the game has to download and reinstall from scratch when it takes that long to write to file. Then again now that I think about it.... that may have been part of the issue of why it's seeing a mismatch error. It should Not have taken that long to write 35Gigs to this Hard Drive.
Am I wrong?
Could the Launcher be incorrect or should I do a full clean re-install just to be sure I have no glitches?
