When starting Quickmap you may get this error:

Cannot save messages to Log file.

Unable to log messages to file ‘c:\qmap.log’ because The process cannot access
the file ‘C:\Users\username\Documents\Quickmap\QMap.log’ because it is being
used by another process.

Error Message is:
                     Found 0 upgrades to apply.

Options are:
                     Abort = Exit Quickmap immediatley (Not recommended)
                     Retry = Retry to save the message
                     Ignore = Ignore the issue and do not remind me again

This happens when either the account you use to run Quickmap does not have permission to write the log file specified in the error, or if you have run more than one instance of Quickmap within quick succession of each other.
