PT 7.3.x,not sure of the latest,and cs rev,should be ok with LP 8.01 on G5.It's working for me,and others.Just a thought,but could a plugin be causing this issue?Try moving the TDM plugs to a safe folder,say "unused Plugs" temporarily,and try launching again.Actually,also make sure that your plugs(especially any rewire stuff) are compatible with pt7.4 while you're at it.It could be an issue with using a G5 quad instead of a dual processor,just stabbing at thin air here....check for a PT cs fix in any case.If you do happen to try re-intalling apps-I suggest installing pt first,and making sure it's up and running,than intalling LP 7 or 8.If you still have lp7 on your system,it should work even if you install LP8 so maybe install lp7 first,than check it,than install lp8 second.Sorry,sounds like alot of time in.
