none of the drive related things made any difference. which is really pinpointing it to cubase, but what the fuck?
i'm reinstalling again. see, the thing is that my reinstall is actually pretty painless - it's entirely scripted. it's just a process of setting it in motion. i have no real fear of reinstalling, it's just a pain in the ass - and a question of risk reduction.
but, i think it's the most methodical way to do this. i want to stop before i run any user scripts, see what happens and then move forwards incrementally from there.
if it's fucked right off the bat...i'm at a loss...
if it breaks somewhere along the way, i can find the problem and correct it.
