I did have it running once already but since rebooting my PC it now crashes X-Plane on startup.
Deleted and reinstalled the plugin and ensured real weather was selected, then it still crashed.
I have tried running FSrealWX first and then starting X-Plane, and I've tried starting X-Plane first without FSRealWX running, and it crashes and indicates the same problem in the log file.
Not sure what to do now.
However when it was working, it was working brilliantly. I have never seen intense thunderstorms and wild turbulence like it, and it was switching smoothly from one METAR to another as I flew the aircraft. So, I really look forward to the final version of this, in the mean time if there is anything else you want me to try with the beta verison please let me know.
