how big are your harddrives? is it possible that they are full and that this file simply can not complete. remember that xolox requires double the amount of space for each file. I run (dont laugh, im getting ready to upgrade) three 1.2 gig harddisks and must use one harddrive to store temp files and another to store them. And yes, i know this is sad, i found out that i had to do this when i was downloading a 700meg file. I have also heard that xolox has problems when a system is fragmented. have you defraged lately?
