Borderlands 2 Sir Hammerlock DLC on Xbox 360 plagued by compatibility errors

Borderlands 2 players on Xbox 360 are having difficulty downloading a Compatibility Update required to play the recently-released Sir Hammerlock's Big Game Hunt add-on, according to a thread on developer Gearbox's official forums.

Gearbox released a new Compatibility Pack through Xbox Live late yesterday, which is necessary to access Sir Hammerlock. Soon after users began reporting errors stating downloads were freezing around the 98 and 99 percent marks. Other players complained of difficulties accessing online multiplayer as well.

"We're receiving reports that some are receiving a 'Can't download compatibility pack' error message while in the process of downloading this content," reads a post from community manager ChrisF. "We're working with Microsoft to address this and expect the issue to be resolved within hours."

ChrisF later noted that deleting past Compatibility Packs for use with previous downloadable content shouldn't effect downloading the latest one. Earlier this morning Gearbox announced via Twitter that the company is still working on fixing the error, and that it would be extending the weekend's Gear Up event until the issue is resolved.

"We're working with Microsoft to get the Compatibility Pack download error on Xbox 360 addressed ASAP — will share updates here as we can," the company tweeted.

Polygon has reached out to Gearbox for more details on the problem and will update this story with more information as we have it.

Update: Gearbox's twitter account still says that the developer is working with Microsoft to fix the error, but has uploaded a Troubleshooting guide for those suffering from the Compatibility Pack issues.
