cant see backed up data with titanium backup


hi guys
previously i had the 2.2 firmware on my Samsung galaxy s i9000
i backed up my memo and messages with titanium backup
and i know have the gingerbread 2.3.4 with root running
i restored my memos but i cant restore my messages
i go on titanium and click restore then it says the message backup is from message 2.2 and i have message 2.3.4 i click restore data it says it restored it but when i click on my message there is nothing there i click on restore data and app it says it restored them both but when i click on message there is anything there. i couldn't figure out what the problem was compatibility issues or anything else need some help asap.
thank you in advance
