Thanks for thinking I'm being so unique , but I disagree. The storage format changed and in some cases, this new BBM can mess up the DB. Could be because my DB contained errors or because I wasn't using the 7bit format. Nevertheless, it should not get corrupted in the upgrade. The only solution is to save all the messages and to start from scratch...I think this is something only you are experiencing
BBM5 is not ready, we all know that, given all the problems that plagued the previous versions (backup/restore didn't work, file transfer didn't work, etc.), but it's almost there , they just need to make the conversion process flawless.
