Uselsx error

I keep getting an “Error loading USE or USELSX module:” when an agent is triggered from the web. The agent works fine on both our development and beta test servers, just not on our production server. The agent tries to use a script library that our team has written and that is what is displayed after the colon following the word module.

We have seen this error before and usually one only has to recompile the entire set of LotusScript libraries and that solves the problem, but this time that is not working. I can run the agent manually from the client.

Does your production server has the lsx? Does it have an outdated version?
