Ah hah! So a Windy Pro is from different provider. Yes? That could well explain my problem. I will go check.

Thanks.

I have just installed Windy 11.8.3. I already have Windy 38 Pro installed but can't log in to 11.8 with my existing account. Can I transfer my Pro account from V 38 to V 11.8.3 - or have missed something?
