Crash and can't/won't go to backups

Doing a standard search for an email sender’s emails, system crashed.  Tried to restore but from both restore points just got this message:
System.IO.IOException: Access to the path ‘C:\Users\myname\AppData\Roaming\eM Client’ is denied.
   at System.IO.Directory.InternalMove(String sourceDirName, String destDirName, Boolean checkHost)
   at DbBackup.FormBackup.Restore(String backupFile, CancellationToken cancellationToken)
   at DbBackup.FormBackup.Restore(CancellationToken cancellationToken)
   at DbBackup.FormBackup.<mainform_load>b__27_0(Object a, DoWorkEventArgs b)
at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)
at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)

Now what?</mainform_load>

Restart your computer and see if the restore will work.

You’re a star!  It worked.  Many thanks for such a quick reply - I’m impressed and will certainly tell others about your excellent service.
