Answer 1

Uninstalled again and downloaded latest version (CS6) from Adobe site - Premiere Pro 6 LS7 (unable to ascertain exact build because crashed again before being able to look at build number)
Running on Mac OSX 10.7.4
Macbook Pro 17"  2.2GHz Intel Core i7
8GB ram
Program opens up windows, followed by Mac spinning ball before crashing
Program had been stable until today - VLC was opened for first time use last night. I uninstalled it before reinstall of Premiere Pro to see if it caused a conflict, but same resulting crash.
No other software running at time of last number of crashes. Macbook Pro is my field machine and therefore has variety of applications for broadcast use (newsgathering use) including Audition, Photoshop and FCP7.
No third party effects or hardware installed
Premiere Pro running with Mercury Playback GPU software mode
