The way I understand it is the amount of tokens you received is fixed. The value of a token will of course fluctuate.

I don't think you need to 'claim' them since etherscan.io already shows them being transfered to you.

https://etherscan.io/address/YOURADDRESS#tokentxns
Replace YOURADDRESS with the address you sent from.

I hope someone will comment if I have this wrong.
