I pledged allegiance to the Aldor and now I can't interact with nobody from both of the factions. I could speak with the Scryers and the Aldor before i completed the <a href="http://www.wowhead.com/quest=10551/allegiance-to-the-aldor">Allegiance to the Aldor</a>. More specifically I actually trained my tailoring and enchanting at the Scryer's Tier and as for the Aldor part I didn't have much to do there but i went to their inn and i could interact with the Innkeeper. But now i can't do anything with either side and i don't have anywhere to train for my TBC part of professions. I can and will provide more info if needed, please help.
You are most likely just hostile or below neutral with both factions at the moment. There is a repeatable daily quest you can do to gain reputation with the Aldor until you unlock the rest of the quests, its Strained Supplies quest#10017
When you reach neutral you can start turning in the marks at Aldor Rise for reputation
Friendly unlocks the rest of the quests if i remember. Players usually become friendly with the first quests unless they pick the opposing faction (draenei in scryers and vice versa). You need to turn in some marks at the rise to reach the needed rep
