Um...any idea what this means?
The system failed to flush data to the transaction log. Corruption may occur in VolumeId: SWTOR_RAM, DeviceName: \Device\ImDisk0.
There is no disk in the drive.
Please insert a disk into drive %hs.)
I guess you tried to trick the software one way or the other. Do "remove and quit" to clean and delete the ram drive. Then play retail or unleashed as you wish (it will recreate a clean ram drive).
