Installed and registered Rescue Kit 14 free edition from Paragon. Tried to create recovery media using an A-DATA 2GB USB flashdrive (1.88GB available capacity). Creation process began then stopped. The following error message appeared: "Operation failed. Error code = 55, error message = Cannot write to a flashdrive, it is locked by another process." The flashdrive is empty and was inserted into computer's USB port just before launching the Create Rescue Media app. How can i overcome this error message, please?
