armis,
This forum is for technical issues with the Flyertalk site.
Sounds like you had gotten an email from ryanair and accidently deleted it. Do you have a "Deleted" folder in your email program? It is possible the email is still there. What email program do you use?
In addition, you may want to post your Ryanair question in the "Budget Travel" forum. Many Ryanair travellers post in that forum.
