FF 4.006 not running under Windows due to networkproblems

I cannot even start the new FF 4.006 under Windows (XP SP3). Never had this problem with previous versions. When trying to start FF 4, I'm getting this error message:

<class XFW::OSCallError> ::GetFileAttributesExW(path '\\?\UNC\?\C:\Programme\Filter Forge 4\Resources', GetFileExInfoStandard) failed with error code 0x000004CF: Das Netzlaufwerk ist nicht erreichbar. Weitere Informationen über die Behebung von Netzwerkproblemen finden Sie in der Windows-Hilfe.

The German text basically says:

"Unable to detect the network drive. For more information on how to eliminate network problems please consult Windows Help."

FF 4 has installed correctly to C:\Programme\Filter Forge 4.
I've uninstalled and reinstalled FF 4, but, unfortunately, to no avail.

Any idea what the problem might be?
Your help will be appreciated.

Thanks for your guess, CFandM!
Problem is, I cannot start FF. When I try to start the standalone or call FF by way of a plugin from inside an image processing prog, I get the error message described in my original post. So, unfortunately, no way using a menu...

Hans-Joachim, this issue will be fixed in the next program update within the next several days.

Hi GMM,
on December 3 you said the issue I have addressed would be fixed with a program update "within the next several days".
I'm patient. Still, a week has passed...
I have a lifetime license. FF has become an integral part of my image processing workflow. That's why I NEED to be able to use the program.

Hi GMM,
thanks a lot!
You should,actually, be very, very LOUD about the "silent" update!
Works like a breeze!
And, compared to the original FF 4.006 version, is lightning FAST!
If I were you, I, immediately, would send a message to ALL FF users / owners, making them aware of the availability of this update which seems to fix a lot of issues.
Excellent work!
