Upgrade from WM 1.25

I cant seem to find the upgrade page where Id enter the serial number (maybe it was sth else, not sure), but I just would pay the difference.

Also, what now that I `ve got one serious bug, which totally corrupts all rendered text around Devices (had that with last few BETAs), what can I do ? Are the bugs still being fixed ?

And I’m pretty sure that Stephen will go on fixing any bug that might occur. He mentioned in the blog that he’s currently working on the next update to fix bugs that were found after the release.
