The day of the weekly trial is Thursday I believe. I think I will either try it out on Thursday or maybe even just take out an annual sub of 25 euro before then.
Thank you for your reply and comments 
Just bought the PMS GTN 750 on the annual 25 euro licence and also obtained a new metar token from Avwx and put the key code in the GTN.
However, I cant seem to get the Metar working in the GTN 750 at airports which have Metar info. eg at the Airport given in the instructions for testing to see if the Metar token is working (LFRK if I remember correctly). Also tested at EGLL and a few other airports without success either. If I press the Metar tab on the weather icon from the ingame toolbar however I do get Metar info for the airports tested so presumably Metar info is working in the sim just not in the PMS.
Not sure what I am doing wrong here since I seem to be doing everything right e.g. using live weather, entering code correctly etc.
For reference I am using the BS TBM 850 with version 2.2.4 PMS together with the TBM 850 WT mod.
Is anyone else having problems with this? If not then probably it’s a ‘me’ problem but for the life of me I can’t figure where I’m going wrong.
If you don’t get the METAR when pressing the test button, this a typo error from you.

Hello All,
As an update to my last post, I did decide to try the free version of pms50 gtn 750 in the Pilatus PC12 and all was fine. If I find myself in one of the other problematic planes, I will try it at that time. For now, the PC12 is my go to in fseconomy.
Thanks and have fun!
