Root problem recovering!!!

[taffy2502]

Hi guys ive recently ran into problems with my O3d and i need to do a recovery on it. I had rom manager on it and i backed up everything before it went wrong but know all my apps and games and stuff has gone including rom manager!!! Ive also tried the volume down and power button but i cant seem to access the restore part of it. I know all my stuff is still on my memory card though which makes it the more frustrating lol. Is there anybody that can help me with this or is it a case of I just have to start again??? Any help would be grateful guys. Cheers
