Lost Access to Account

Hi there.

I played on this server when it was still 5.4.2 (The Frostwolf realm). I had a mage (arkainz. 522 ilvl frost/arcane) and a shaman (Iconixx. Low ilvl ele). Since this time I have been on a research excursion with my university. I am now trying to log into my account and am unable to... I created this account to post this.

I know its probably lost forever, but I would like to know what happened. I never got any emails or anything saying passwords had been changed etc. Was it deleted due to no use?

Please advise, I would really like to play here again. And would prefer to play the characters I previously had, as levelling is aids.

thanks :)
