I would appreciate any help on this problem.

Ioncross was running fine with no problems.
Our office block had a power failure due to redevelopment work going on at an adjacent building.
When Ioncross restarted, it processes the player files and then stops and returns this error:

Run Time error 55
File Already open

Press ok, and then it closes. I have the player files backed up, but is there a solution to this rather than restoring the previous days files?
