Unhandled Exception Won't Allow Playback

[steve]

If you select one track, then use "Mix and Render" it will produce a rendered version of that track in which envelopes and pan positions are applied and gaps between audio clips are rendered as silence. If you do this for each track, then the tracks can be Imported in to another project and everything should line up.

I try to open the project from the .aup file, however when I select 'Open with' and select the 1.3 version of audacity, windows still opens it with the old one

That shouldn't happen, you should be able to choose whether to open in 1.2 or 1.3.

This happens because you can't point "Open with" on Windows to two executables with the same name. Rename one of the copies of audacity.exe to fix it:
