maxima doesn't start



Hi!

I installed maxima 5.12.0 on my windows xp (I don't have a firewall). But  
the back-end doesn't start.

When I call maxima.bat from the command-line, it terminates imideatly  
without any output. I found out that maxima.bat calls maxima.exe as  
follows: maxima.exe -eval "(cl-user::run)" -f
doing this manually produces the same result as from batch-file.

When I call maxima.exe from the command-line, it terminates imideatly  
after the following output:

When I call "maxima.exe -eval" from the command-line, I get following  
output:

and a prompt - but I don't kwon what to type as it seems to be not the  
intended prompt.

Has anyone an idea what could I do to make maxima run on my maschine?
Or what can I do to further debug the problem?

Thanx,
