I have a problem with my Mitsumi CD-Rom drive. I had to install it on DMA channel 6 instead of 5 because of my Ultrastore Controler Card but after many hours of playing "autoconfig leap frog" it finally worked ok. Then, I installed both CD Player and CD Trakker 1.5. They both worked ok too. On a whim I tried to read a music cd, which of course was impossible. After that read attempt I could not read another CD, except for the playing of music. Everytime I tried to do just a DIR I would get: CDR103: CDROM NOT HIGH SIERRA OR ISO 9660 FORMAT READING DRIVE E: I tried everything including relaoding the CD drivers. I'm using MSCDEX.EXE VER 2.22, which I got from here. I am so $%#$%@# tired of incompatibil- ities. I even called California and spoke to someone there who didn't speak English very well. All he told me to do was reload the software, I think. I tried different CDs, MG! I was able to read the CDs on other systems that I couldn't read on the Mitsumi. It appears that the loading of one of those music players (CD Player or CD Trakker 1.5) contains the missing factor. I also had to load into the Windows system director VBRUN001.DLL (or some name like that). I have no idea where to go from here. Any help will be greatly apreciated. Dennis
