So I have purchased songs on the music store, and Rock Band 3 ran through emulated NAND (hard drive), through uLoader 5.2/5.1E. Problem is, quite a lot it will fail the download. And when it DOES succeed it often crashes when 'loading new content' on the main menu. This means I have to open up the hard drive on my PC and (somehow) find/guess which folder contains the new 'problem' song in order to get the game running normally again. I have wasted literally days and have only managed to get about 15 extra tracks loaded successfully. Argh! Is this a known problem? Or could it be a problem my end? I have the latest ciosxr21 installed to ios 249 with ios58 as base and hermes 223 v5, er.. ios 37? I think? Is that correct? I have only had problems since using uLoader+nand, although of course I never really used DLC with it. I have followed so many guides but none I have read about explain the error I am getting apart from on the uLoader 5.2 thread... but I have the same problem with 5.1E also, so can't be that. Any advice? Any help would be appreciated.
