Cannot open last session!!

Mixed my first song in Mixbus 2.0.3 and saved the mix and saved a snapshot of the mix. I need to tweak it and now cannot open either one??? Realized that there was an update to Mixbus and applied that. I am now at 2.0.4 built from Ardour svn 10033. How far along is this in relation to Ardour on it’s own? Any help is surely appreciated as this band is a great client and I do not want to lose them.

By the way I am running a G5 dual 2.0 ppc with 5 gigs of ram and OSX 10.5.8 updated.

Make sure you drop an email to Harrison. Also you can try to catch them or myself(Unrelated to Harrison but I can often help) on IRC by going to Help>Chat.
