Dropped from lvl 29 to lvl 0 ??

You didnt drop friend, you simply are in the land of limbo! This magical land is the place before you prestige :) 

Have the same problem. How did you solve it?

Earn more ARP until you prestige :) 

Understand, but why I can not join to giveaways 20+? I thought it is because of 0lvl... (And I was 30;))

Because you guys are new: https://na.alienwarearena.com/faq-contact#ARP3

I can't explain why you don't have access to a particular giveaway, because it is either that you aren't on a master level tier, or that the giveaway ran out of keys in the pool so it was too late for you, which is all likely why you can't get a key.
