I bought Sonar back in October last year and it's been running fine. I did a massive amount of work to a tune yesterday (mostly audio files, some stuff on NI Kontakt) and saved it. When I came back to it later it loads and then Sonar crashes. I've tried other arrangements (stuff way more complex than this) and there is no trouble however I can't get this one track to open.
Any ideas would be gratefully recieved. If I could at least open the file so that I could recreate what I've done I'd be grateful, basically I'm on a really tight timescale to get this done.
