GTA IV: "You don't own this game"

Hello. I've been having an issue with my digital copy of GTA IV. I purchased the game a while back, played it for months, and then took a break to play some other titles. Now, suddenly, it's telling me that I don't own the game. Every time I go to
play it, it gives me the option to purchase the game, and that's it. It's as if I never owned it, and yet I have played it for countless hours, earned many achievements, and recorded plenty of clips. I purchased the game digitally, it's still installed on
my console, and I have never played it on a disc. I'm just clueless as to why I suddenly can't play a game that I definitely own. Any solutions would be appreciated. Thank you.

:)

 

Anyone else worried about GTA:V frame rate issue's?

GTAIV was only following the timeline from GTAIII (which was also serious) and don't anyone bother saying that they didn't like GTAIII

[/quote]If I remember right, Rockstar considers the PS2 GTA games as their own separate universe from the "HD GTA" such as IV, its DLC and GTA V. Consider it like an alternate universe.

 

That street criminal in gta v's trailer looked like CJ

"Each GTA is in its own era, therefore characters from the GTA III era cannot exist in the IV era."

Does this only work for the numbered GTAs?

Because Claude and Catalina show up in San Andreas, along with a bunch of other characters popping up.

 

And... now it's not letting me edit my own post, but to clarify, I meant GTA V, not four. Sorry about that.
