My support package is is just expired so I cannot communicate with Acronis directly sorrows wondering if anybody could help me with the above error log?

I've been getting various error messages like license file corrupted, so I re-imported them from a text file.

I also got an error message previous to this say that my license didn't cover backing up certain type of files but I wasn't given any indication what these files were and that error message has ceased.

Any suggestions as to where to go to understand the above error code as sending it to the default Acronis server for examination resulted in no results.

Any help much appreciated
