It is when you try to print that causes the error? At what point does the problem occur (does the report begin to compile, select records, start to print to paper, etc)?

Do you have any other modules that use the Crystal Print Engine (such as Accpac for Windows)? There are a couple known issues with ufl files in the \winnt\crystal directory. The specifics are on another post (April 1/1999) in this forum.

Do you have a selection formula for these reports? If so, please remove it and try again. If not (or even if so), try to restrict the data even further (ie just for month to date or something like that).

Which modules are these large reports based on (AR, GL, etc)?
