I love the way I can group tracks together. I like the ability to do MIDI tweaks. I feel comfortable working with Sonar- just upgraded from X1c to Platinum.
I hate the fact that my old BUN files are forever lost. How can I forgive Cakewalk for that?
I had a lot of work in those .bun files. Why isn't there some kind of conversion app for them?
I have some problems being organized with plugins/folders. Maybe there could be a better
Sonar structure for those. Some folder locations work, others don't.

Are you using 32bit Platinum?

 All of bun files from back when I was using Gigastudio 3 open up.  I no longer store projects in a proprietary format. You could try renaming the extension .zip and see if they open.

Back everything up.

Upgrade to Sonar X3E. Open you bundle files and save as projects or CWB files. Then open and save in Platinum.

KiteKrazy,
there is nothing wrong with the BUN files.
SP can still open them up.  Matter of fact, I opened one up from Pre X1 days and it worked just fine.
Of course my set up was a little different so Sonar let me know I didn't have those VSTs anymore on my computer but the file DID open.

So I guess the moral of the story is... if there is a hole in your bun, plug it in?

Old bundle files should definitely open in Platinum if they did indeed open in X1. 
If not send a link to a sample BUN file that doesn't open and we can look into it. 

I stopped using bundle files eons ago back in the early days before SONAR, lost too many projects forever.

That sounds like the place to start troubleshooting, not SONAR.

...and the early days of storage media. I'm trying to remember if ANY Jaz or Zip disks didn't fail eventually.
