is there a way to check if i have received any thing but it's not shown because i didn't add the token ?
You can go on https://etherscan.io/address/YOUR_ETH_ADDRESS_HERE .
There you can check 1) your ether balance and TX's and 2) token transfers to this account.
To make it visible in your MyEtherWallet instance you have to "add" this token. You have to enter Name/Decimals/Contract Address of this Token to make it usable.
From there on you always see those tokens when loging in to MEW and you can send those.
Exactly what i was looking for
Thank you for your help
and thanks for everyone else
