I noticed this error for the first time on Friday while working remotely. Never have issues with Monarch and wonder if this is a network issue for me? While waiting for my export to run (sending to excel via a mapped network drive) it appeared as if another instance of Monarch was trying to open so I opened my windows task manager "application" window and noticed 2 applications appearing. One was to open the export and the other was to save the export. I did a test and ran the same export but this time sent the export to my local drive. No applications ran in the windows task manager "application" window and the exports ran as they normally do.
Would this be a network connection for me? or is there something that needs to be updated on the server I'm sending the exports to?
