Suddenly I get this error and don't what to to. Tryed to reinstall.

suggest you open a support ticket!

From the knowledgebase -

 

"We believe this is caused by a corrupt file in the AS2012 installation (.xml file).

Please re-install AS2012, by uninstalling and removing all saved data, then reinstall... removing the saved data is important to remove the corrupt file and allow it to re-generate.

You can keep your "Snapshots", but all other data should be removed before installing again.

 

If this does not solve the problem, please open a support ticket."

 

If you are running Win7, everything in C:\Users\(Your username)\AppData\Roaming\HiFi\AS2012 except "Snapshot" is what should go -
