This error has to do with the user access rights.
This generally occurs with a new PC, attempting to run TM5 for the first
time. It’s looking for DTMON.DLL in the System32 folder.
This is generally caused by a failing network switch, card, or router.
Replacement or the bad component is the solution.
It has also been caused by anti-virus / anti-spyware programs aggressively
checking every file. This causes system slowness to the point where this
message appears. We suggest that you set your av software programs to skip
.DBF, .CDX, .FTP and .TXT files as a test should you receive this message.
This message might be displayed when sending a fax or printing a letter using mail merge.
