Is it only one machine that is erroring?
Don't know if this is of any help or if it may apply. I recently created an MDB on my personal machines running XP-Home and XP-Pro. MDB would not install onto my work machine running Win2K, but did install after XP-Pro was installed. HOWEVER, the MDB kept failing at several VB
and built-in functions (getobject with same error description you are getting, date() with #ERROR, forms that just corrupted after being opened in design view, and several other very annoying things just slowly started failing). After our Tech re-installed XP-Pro have had no further problems. Both machines have full A2k licenses. Have not installed our MDB on any of our machines with A2K Runtime and have not tried the file as an MDE. Just a thought, you don't have "add-ins" that Package and Deploy missed?????
