OLE and Excel

I've been playing around with OLE and embedding a MS Excel document. The MS excel document has an auto_open macro which loads a comma delimited text file created by another part of my application. The problem is that I get one of those awful DR. WATSON messages for Windows NT with the error:

Exception Access Violation (oxc0000005), Address: 0xc30085lfa.

I have no idea what this means. If I just keep hitting the cancel button on the Dr. Watson notice eventually the Excel document loads and runs fine. I just wondered if there was a reason for hte Dr. Watson notice and if there is any way to get rid of this.

Also, instead of the vba macro is there a way to load the text file into Excel using the OLE container?? Just curious.
