It looks like it may be. I did the database rebuild and file system restore before downloading/installing as well. Still, it shouldn't have to be the solution.. People should be able to enjoy the game regardless of the avenue they took to purchase it.. it's a shame that some people are getting these issues with the game, that would drive me bonkers.
I tweeted them this thread. No reply, as expected.
Exaclty! Why should i pay $150 for another hard drive to play their game? They should have known that this was going to happen.
Did u try @RockstarSupport ? Looks like they are the only ones replying
