As Kaarel already wrote it is difficult to answer without further  
details. Please send me your axioms and your query. Be aware that I am  
in vacation in Sicily and not permanently connected to the internet.

I just ran RACE successfully with 13 axioms and got an answer in .5  
seconds.

The error message that you got is not generated by RACE itself, but by  
its web-service. Try to submit your ACE axioms and your "what"  
questions directly in the RACE web-client. Possibly you need to prefix  
unknown words by their word-class. For details how to prefix see the  
help text of the APE web-client.

Currently, RACE can only be used via its web-client. A public release  
is planned for later this year.

Best regards.
