I would suggest you to go to etherscan.io, insert your address in the top right side of the page.
You will see a page like this one
https://etherscan.io/address/0x86fa049857e0209aa7d9e616f7eb3b3b78ecfdb0 Then, click on View tokens, and you will be able to see all the tokens you have, without inserting your private key.
Alternatively, you can use MyEtherWallet and insert the private key there.
Let us know!
It's saying that i have my Omisego maybe my wallet only support ETH but is not ECR 20 friendly i will try to insert my key on myetherwallet.
