I am using Adaptec 4.01. EZCD Creator & Direct CD run fine. When i go to Adaptec's site and download the 4.02 patch, EZCD Creator & WinOnCD Power Edition will not work.
I have the PlexWriter 12/4/32, firmware 1.04 and Clone CD PlexTools, PlexManager 2000, Adaptec 4.01, and WinOnCD Power Edition running on Windows 98.
Any ideas? Thanks in advance.
