"Failed to load textures" back again

Odd, I had this problem previously with my Cheyenne and it went away after I uninstalled and reinstalled the airplane. But now I'm getting the same problem with my Dakota and uninstalling and reinstalling doesn't make any difference. I get the following - "Failed to load texture : VC4T_BUMP_PSD.DDS" error message and since I've had it with 2 different aircraft sources I don't believe that it's related to the particular airplane.
What I've done:
Uninstall and reinstall 3 or 4 times ...
Reinstall vcredist_x86 (I know, grasping at straws here)
Tried ALL the other Dakotas .... same thing
Installed the latest Nvidia driver ... 75.19 (after a drive sweep)
Remove the mild oc I had (was 2.7, now back to 2.4 Ghz)
Check for disk errors
Copy the file DF236_VC4_T.DDS up one directory (my thinking was ... well, maybe it needs some help finding the file ... (I think this is the file)
O&O defrag .... I know ... but why not?
It seems something has flipped since it DID work correctly about a week ago ... and I haven't done anything drastic since then.
If anyone can shed some light on this for me ..... Nick? (When you are not swamped with all our pleas for help of course)
