I have 2 versions on same PC (11.26 and 11.30 beta ?). both seem to update OK, although 11.30 took very long to check the files and then very quickly updated with a very small file (10 MB ?).
Starting up after update, both versions hang. (black screen with little circle)
Later message: no response from X-plane.
I bought X-plane at FS-Pilot (order #952589) and I have the productcode.
