Hello Dup,
which plug-ins are you using in your VE PRO with that song?
Maybe you´d like to send it to support [at] vsl [dot] co [dot] at, so that we can take a look at it - please include as many details as possible, preferrably also screenshots.
Is this the case only with this song, or do other songs behave the same way? Do the have something in common (like a 3rd party plug-in)?
If you delete some of the additional plug-ins, does it open then? Can you save the VE PRO project (viframe) and open it again, in a new instance of VE PRO with the new version?
Thanks,
Paul
