Game error 201 - Reinstalling DDO

[Slapphappy]

I have a PC desktop that is about 3 years old running Windows 8. When I first got the system, I loaded DDO on it and it worked great. Then I used the uninstall feature to remove the game (spousal aggro) and was playing DDO only on a laptop. I recently downloaded DDO on to the desktop again. No problems until I try to open the game.

The game updates fine.
The login screen comes up fine.
I login and choose my server.
The load screen comes up, and then a ding and a window pops up with this message,
"Game Error 201
Can't open data files. Check that they exist and that you have permission to write to them.
The program will now exit. [201]"

Advice?

Check the install folder and make sure the DAT files are bigger than a few kilobytes, if they are not then they are missing. If you have a working install elsewhere then you can just copy the files over.
