The 'Dawnguard' PS3 release was delayed last month due to technical difficulties. Sony's Adam Boyes confirmed that both companies were "trying their best" to resolve the issue.
"We work with all of our partners to try and solve their problems," Boyes told Kotaku.
"We have a big, broad dev support team that works closely with Bethesda - and with all of our partners - to... solve any sort of issues they have along the way.
"Of course, I always want everything to work always for everyone.
"I can't promise any kind of resolution or timeline but can say that everyone involved is trying their best to get this stuff working."
Bethesda had previously stated that it wouldn't release the expansion for PS3 "knowing that some people's experience in Skyrim will be worse", confirming that the 'Dawnguard' release was in jeopardy.
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.
Bethesda recently released the 'Hearthfire' expansion, which gives users the opportunity to buy land and build their own homes.
