Corrupt License Files
I'm posting this here to widen the reach of my announcement.. embarrasingly I have been sending out corrupt license files to recent customers and with the trial version you can download from www.DozingDogs.com. 
All customers affected have been updated, but it's hard to reach people who have downloaded the trial version recently. If you see an error when you save content please download an updated license file and place it in your Web folder.
Note that this error is only annoying; your content has been saved correctly before you see this error. I'm not mean enough (or stupid enough) to check the license is valid before saving the content.
