First of all - thanks for release

However I cannot celebrate it... yet.
I've downloaded an update thought Beta "Check for updates", uninstalled the old version, installed new one and decided to make a simple scene to test this new TG2 and apparently I can't save .tdg files. Every time when I choose to save it I got an error message:
"The Project file has not been damaged, but any changes have not been saved."
Which results in writing a 0 byte .tgd file.
I've tried reinstalling TG2 together with cleaning the registry with no effect. Any idea what might be causing this strange error?
