Build 319 has a completely rewritten Serialization system. I've moved away from Microsoft's XmlSerializer in favour of versioned Binary files. If you were exeriencing crashes due to code generation or permissions on the temp folder these have now all been fixed.
During installation Build 319 will upgrade all of your existing data files from xml to bin. A backup will be created in case there are any issues.
You can grab the build from the Product page or use the Update button in the Options Window of Startup Delayer.
