I am ready to throw in the towel! I feel like SOS when he was building his system a few months ago where nothing was going right...This has been a disaster of monumental proportions! Just to update, I upgraded to SX 1.05, didn't work, either did the rollback to 1.03. System was completely unusable. Uninstalled SX completely, reinstalled from the orginal CD, same exact problems...the uninstall routine left some latent files on the system...couldn't recover. After over a week w/o any workable system, and no good advice on how to recover, I decided to do the only thing left...reformat, and re-install. Crap! OK...2+ days of reformatting, and re-installing Windows, all the updates, VST 5.1, Wavelab, Waves (and reauthorizing ), UAD-1, etc...3,731 reboots later... I finally am ready to reinstall Cubase SX... Now my friggin' CD ROM is unrecognized! It shows up fine in the BIOS, but not in Explorer or My Computer. In the Device Manager (Win 2000 SP3) it shows up, but with the dreaded yellow exclaimation point. When I go to "properties", it tells me that the device has a "code 19 error", or "code 14 error", or something like that. Something about the registry possibly being corrupted. What the...??? Why me...??? I uninstalled, and reinstalled, modified the registry (just so it would write to it and resave it), reinstalled the drivers, rebooted 5 million times, even unplugged it from the IDE controller... you name it, I have tried everything I can think of. I am out of ideas, frustrated, and still without a system. Any ideas would be greatly appreciated.
