We have 4 computers which are running Impromptu scheduler to print reports each morning. On one of those PC's for the past 2 days all reports have "error-ed" out. All of our reports are running off of 2 catalogs which reside on a server. I attempted to insert a task on that PC which accesses our titles catalog. I get the error message: Error Number: 24641;Impromptu cannot open the required catalog. I checked the Scheduler help text and it talks about the username or password changing or the catalog being renamed or deleted. I don't think that is the problem due to the fact that the other 3 PC's are OK. I attempted setting up a brand new PC and trying to schedule reports on it but I get the same error. On that one troublesome PC I can however run any report if I open them through Impromptu. Any ideas on what's going on?
