If there is a second part (that you did not mention
previously) then that was NOT the complete error
message! :-)

If filepro can't open the error message file, then I
would hazard a guess that your problem has to do with
and environment limit on either the number of files or
buffers, or something like that.  I'm not windows
expert, but I know that this is configurable for each
command prompt - the number of files and buffers that
you can open at one time.

I hope this helps.
