Exception after moving ProgramData (1 Viewer)

[josjojo]

Because the ProgramData folder of MediaPortal was very big, I robocopied the files from C:\ProgramData\Team MediaPortal to D:\ProgramData\Team MediaPortal (with file permissions copied over). Thereafter I made a symbolic link (Directory Junction) from the folder on C to the folder on D. Now when I startup MediaPortal it hangs at the full screen loadingscreen.

I opened MediaPortal with the Watchdog. In the MediaPortal.log file there was the following exception (description is in Dutch):

When I start MediaPortal as Administrator it runs normal.

What's happening here? How can I start MediaPortal as a normal user again?
