Convert HDZIP Files Problem

[Ernie]

My Convert HDZIP files keeps stopping at 17358 of 25454. A small square box with the word hoster on it and a red circle with an X across it, and also a button that says OK on it. If you push OK, then it dissapears and underneath is the Convert HDZIP Files Box. If you hit cancel, it dissapears, but if you hit OK, then it just starts all over again stopping at 17358... Any ideas???

Thanks,
Ernie
