VarAC - FM discussion forum

I recently installed WSJT-X on my computer where I have been using VarAC for a long time. Now when I start VarAC and double click on one of my saved profiles, I get the following error:

00:54:37 - Error: doubleclicik on relay message notification failed: The system cannot find the file specified

   at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)

   at System.Diagnostics.Process.Start()

   at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)

   at System.Diagnostics.Process.Start(String fileName, String arguments)

   at VarAC.Form22.datagridview_relay_notifications_CellDoubleClick(Object sender, DataGridViewCellEventArgs e)

The various profiles are located where they have always been, I just can no longer access them. VarAC still seems to function, I just can't change profiles any longer.

Any thoughts to guide my troubleshooting?

Thanks!
