FCP 7.0 Crashes at start up after first installation

first i must say I am still running on Snow Leapord. now, I've previously tried to install older versions of FCP by downloading torrents so i always figured the crash was due to currupt files. But Today I installed FCP 7.0 with the legitimate disks & with a legitimate Serial Number.

Before this install, i Uninstalled all FCP files with FCP remover AND CleanApp

the install went smoothly, motion works, livetype works, color works...all other programs in the FCP studio works fine so far EXCEPT FCP itself. i do not even get as far as the splash screen. the icon bounces on my dock then i get an error message.

ive tried preference manager on Digitalrebellion.com and i also tried to open it after deleting Qmaster...

this is an app that ive been in need of for a long time now! i do not know what else to do.

PLEASE HELP!!
