When syncing an MSP project with Daptiv Project Transit, user is getting error from the wizard such as
"System.Runtime.InteropServices.COMException (0x800A044D): The argument value is not valid."
This is not linked to the Microsoft project version.
1. Open the file in MS Project then go to File > Info > Project Information > Advanced Properties > Custom Tab > Properties Box (Scroll Down and select PTProjectID)
2. Delete the Value in the Value field > OK
4. Then try to re-sync.
