DriveClub's servers currently cannot cope with the number of users attempting to connect their copy online. The problem started before the game even launched on disc in Europe, and has caused the free DriveClub: PlayStation Plus edition to be delayed until further notice.
Evolution has been forced to implement a one in one out policy - so you won't be able to log in unless another player disconnects.
Director Paul "Rushy" Rustchynsky has now defended DriveClub's troubled launch and said that pre-release tests had not shown up any issues.
"We ran a beta test and none of these issues occurred," Rustchynsky wrote on Twitter. "We had confidence everything was ready. These issues were unexpected.
"We did run large scale synthetic load tests with tens of thousands of concurrent users and the tests were successful."
Some DriveClub owners have questioned why the game was released at all - especially after its previous year delay - if its servers weren't ready.
Others have asked for compensation - something Evolution has said it is not against as a possibility.
"We're considering all of our options right now," Rustchynsky wrote in response to one fan who had been unable to connect.
The last server update, pushed live on Friday evening, increased the total number of players able to connect. But Evolution explained that further tests over the coming days would impact server availability for all.
Even if you can connect to the game's servers, various features remain offline. Challenges and social updates are unavailable, although clubs, leaderboards and online racing are enabled.
"We're still working flat-out to fix the online problems," Rustchynsky concluded last night. "Sorry for the wait."
