URGENT: Motion Downgrade crashes too??!!

getting really desperate here!

and realizing the dependency on applications and not being able to work right now!

fortunately I finished a big project in the older version before updating to 5.0.5!

Motion 5.0.5 keeps crashing on launch ("Project Browser" windows shows up briefly)

I followed all the good advices:

- deleting ~/Library/Application Support/Motion/Layouts

- deleting ~/Library/Preferences/com.apple.motionapp.plist

- Running Pref_Man

but Motion 5.0.5 keeps crashing!!!

now it's getting really desperate:

then I tried to go back to 5.0.4 and with "Time Machine" I replaced:

- /Applications/Motion.app (5.0.4)

- ~/Library/Application Support/Motion

- ~/Library/Preferences/com.apple.motionapp.plist

crashes, crashes and crashes on launching!

please HELP!!!

Mac Pro running 10.8.2 (The Lion's ... my biggest mistake)
