I just installed v126.96.36.1995 on a new laptop, and followed the instructions at Migrate Settings to New PC to move my settings to the new laptop - I copied the contents of c:\users\application data\quest software\toad for data point 5.7" on my old laptop to the corresponding folder on the new laptop. Before I copied these files, TDP opened fine with no errors. Now, the first time I opened it, I got this error:
Could not find a part of the path 'C:\Users\dbean\AppData\Roaming\Quest Software\Toad Data Point 5.3\ModuleSettings\ProjectManager.tpf'.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite, Boolean checkHost)
The Navigation Pane opened, but it was empty, so I tried closing it - now, TDP opens without error, but I get the error if I try to open the Navigation Pane. I can open the Connection and Object panes without issue - those are the only other components I've tried.
