i just upgraded (via the downloads available on apple's web site) from OS 9.0.4 to 9.2.2 (i did all three downloads in sequence) and now photoshop won't open. quark is still working, and it appears most of my other software (reader, etc...) is also working. it gives me a type 2 error when i try to open photoshop, which i know relates to memory. but i tried adjusting the memory allocated to photoshop, and i'm not running any other programs simultaneously, so it seems unlikely to be a memory shortage issue. has anyone else experienced this? anyone know a solution? i've tried reinstalling photoshop and i just get the same error type 2 message when i try to open it. i did get a couple of errors while installing the OS upgrades-- something about shrink wrap and i think the other one was error type -39. i actually tried to cancel out of the installation process at one point after getting an error message, but it just kept right on trucking in spite of me. any help greatly appreciated. i'm woefully inadequate when it comes to tech issues.
