Excited to get it on with the new 2.0 version.

But before going all in on the 2.0, I wanted to make sure my songs will work with the latest v1.20.
Have some projects that I think uses the 0.97 and/or 0.98 versions. These sadly won't work properly with v1.20, and thus probably not with v2.0. (KarmaFX Synth has no sound because it ends up with an empty patch in this case.)
I guess there is some compatibility issue between v0.97 and v1.20, and so I have been trying to get a hold of the old versions, but the links to these are no longer working.

Is it possible to get ahold of these older versions, or is there some other way this can be solved?
