'Dawnguard's PS3 release was delayed earlier this month due to technical difficulties, which Bethesda confessed are still to be resolved.
"It's been a few weeks, and we wanted to make sure everyone knows where we're at with 'Dawnguard'," writes an administrator on the Bethesda forum.
"Skyrim is a massive and dynamic game that requires a lot of resources, and things get much more complex when you're talking about sizeable content like 'Dawnguard'.
"We have tried a number of things, but none of them solve the issue enough to make 'Dawnguard' good for everyone.
"The PS3 is a powerful system, and we're working hard to deliver the content you guys want. 'Dawnguard' is obviously not the only DLC we've been working on either, so the issues of adding content get even more complicated."
Apologising for the delay and promising to keep users informed, the administrator was unsure whether or the not the problem could be solved.
"This is not a problem we're positive we can solve, but we are working together with Sony to try to bring you this content."
Bethesda had previously stated that it wouldn't release the expansion for PS3 "knowing that some people's experience in Skyrim will be worse".
Skyrim's 'Dawnguard' DLC includes a new plotline where players can choose to align themselves with an evil Vampire Lord or join the ancient order of Dawnguard to stop him.
As well as a new faction quest line, the pack features additional locations and the inclusion of crossbows as a weapon.
Earlier this week, Bethesda announced the 'Hearthfire' expansion, which gives users the opportunity to buy land and build their own homes.
