I have a similar -- and very vexing -- problem with EOS tokens: I bought some on Kraken a few weeks ago and have had them safely stored in my Trezor.
A few days ago I saw the need to "register" them so that I don't lose them when the EOS genesis block is created next June.
So I read a bunch of tutorials on steemit.com and created an EOS public/private keypair at
https://nadejde.github.io/eos-token-sale/ so that my tokens can be "mapped" between this EOS public key and my ether address, so that it'll be known where to assign my tokens when the EOS blockchain is created. The mapping checks out OK and appears to have been done successfully.
Then I followed a tutorial explaining how to "register" them using MyEtherWallet. And it seems to me that the process of registering them, AFAICT, was to send them to an address to enable this registration, which was in fact to move them out of my custody. Once they're registered, there is a process to now "claim" them back. (Actually I registered them first, and then did the key-mapping.)
My problem is that I've tried several times to claim my EOS tokens (making sure to wait until after the specific 23-hour "contribution window," during which I registered, has ended, before I tried to claim), wasting gas (a silly name for transaction fees) by making repeated transactions.
But I have not yet succeeded in claiming my tokens. After my first couple of tries I realized that I was "out of gas" - i.e., I hadn't allocated enough ETH for the transaction to be processed.
After making sure I had sufficient gas, I tried again to claim, using the "create custom token" link in MEW, pasting in the correct address, adding "EOS" for which token, and "18" in the box for decimal points, all as advised in a tutorial for claiming. but every time I finish the process, (click "write" etc) and I look for my EOS balance, it always comes up zero.
I'm finding this process to be some rather exotic stuff - I've had to do an awful lot searching to get basic info, and the tutorials, well-meaning as they are by the folks who take the time to write them, are often flaky and incomplete.
I see it's written above that claiming is needed to be done only by those who got their tokens directly from the ICO, but I now need to claim, in some form or other, just to get my tokens back to someplace where they're under my ownership and control, or at least to someplace where I can see my balance.
I also saw, on a thread on the EOS reddit, where someone said to log onto "the EOS private server" to see unclaimed tokens and that "it's in their instructions," but no link was provided, and I looked through eos.io for some mention of a "private server" but found none.
If anyone can shed light on how I might resolve this, it would be great. I've been seeing plenty of other complaints, btw, of folks not being able to claim their EOS tokens. FWIW, I'm in the US.
