Thank you for your response, TG :)
I also guess that this trouble probably occurred accidentally by other reasons  when SkinBlender is installed.

I don't know how picky Poser is, but since I think this is made on a Japanese system,
there COULD be a stray character ro klanguage coding or whatever somewhere.

I've heard that there are products that won't work on Japanese or German Poser installs.
Since I'm using an English Poser I don't know for sure, but that might be the cause.

Yes, My development environment is "English  version Poser" and "Japanese version WinXP".
I also experienced that errors occurs by some programs in Japanese version Poser or Japanese version OS.
These most causes are insufficiencies of avoiding processs of "errors of language encode/decode" in these programs.

Of course, I add avoiding processs of "errors of language encode/decode" to SkinBlender.
These process are performed on Python interpreter level without OS.
Therefore, I cannot guess "a possibility that the trouble of OS level will be caused by SkinBlender."

Addition:
One of the causes which a TEMP file damages is a trouble of HDD.
Even if  you do restoration and re-installation of a Win system, unless the trouble of HDD is solved, a new trouble may occur.
First, please check the condition of HDD.
