I have no idea if this will help (and you may have tried it anyway) but, just before you try the APPEND command check
DBF("MyCursor1")
FILE(DBF("MyCursor1"))

DBF("MyCursor2")
FILE(DBF("MyCursor2"))
I don't know what it would mean, but it might be interesting if neither DBF() command gave the same file name as in the error message.

and, since nothing else seems to have worked, how about trying a FLUSH just before doing the APPEND
