Can you split import of one table into multiple parts?

>OK I solved the first problem by converting the fields from text to memo. (That's not really a solution but it took care of the immediate issue.) The second problem turned out to be invalid ASCII characters in the memo fields. Apparently the data entry folks are sometimes clumsy on the keys. But now I have a third new problem. While importing a very large XML (39 meg) consisting of an integer field and a memo field, Access gets to around 1300 records and then hangs with no error messages at all. My various data checkers don't find any problems with the data. More ideas?
