I'll assume you loaded any file and the file system locked it (corrupted). Few things you could try first; one being to ensure you are logged in/key'ed in the manufacturer access level, second would be a sys shutdown/reboot, third would be to using the Siemens' Access MyMachine P2P software for file system access when the ctrl in on reset (if you have IP networking interface).
Where are you in the debug? What steps have you already taken to try to get this sorted?
