I just downloaded Burrn 1.10 so that I could write my non-compliant multiple FLAC cue sheets to CDR, but after using the installer and trying to open Burrrn, I get an error window: "Error: Runtime error 216 at 00404096" (number is always the same) ...any ideas?

I get the same thing sometimes. I use it for the same purpose, and it's CUE fix tool is excellent for quick renaming of .wav to .flac and fixing the long pathname. As far as the runtime error, I find that if I just keep starting the program over and over that it eventually fixes itself. I wish I had a better answer for you, but it works. Hopefully someone else with more knowledge about the program will respond.

What OS are you using?

If you're using Windows XP, I fixed this error by running it in Windows 98 / Windows Me mode. I've never had a problem since. Just go in your Burrrn.exe properties, click the Compatibility tab, and check the box "Run this program in compatibility mode for:", then in the drop down menu, click on "Windows 98 / Windows Me". Should fix the problem.

I'm on WinXP. I'll give that a shot next time it crashes. Right now, simply putting wnaspi32.dll in the folder seems to have helped a little. It still crashes some, though.
