I installed Toast Ti 7.0 out of the package before 10.4.3 came out. I've burned cd's and there wasn't any problems. I downloaded the next update (10.4.3) and which didn't download properly. I re-downloaded the package separately on my backup startup system, ran the update on my primary system, rebooted and thought all was okay. I then tried to launch my ToastTi7.0 and it just bounced around and eventually (10-15 sec) stopped like nothing happened! I can use my optical drives okay so I know they work fine. I thought that maybe there was an update and there was - 7.01 - I downloaded that and replaced 7.00 w/ 7.01 with same results. Any thoughts?
