Hi Ludrick,

1. Call up, Preferences, the indented wheel cog icon at the top middle of the interface.
1-1 In Preferences, go to the File page and alter the Export location to a more conveienet position. I use a folder with a project name and have it on a different hard drive.
1-2. All save as project files and exported data will go to that new folder.
2. Use File > Save project as, and name your pds file. Save this way regularly.
3. Re-your DVD 8.5 discs.
3-1 Are they the correct discs for your drive, you need to check.
3-2 Alter the selection in the Create disc folder.

The above are all best guesses. Please read the guide.
