Internet node token stuck on etherdelta

I traded a number of INT on etherdelta a week ago along with some other tokens , the other tokens are in my trezor but ED wont let me transfer the INT tokens. I was wondering if anyone else has had this issue ? Ive tried about 5 times to move them , when i check the transaction on etherscan it says 'fail' warning, error occurred during contract execution.
Why would this happen?
Any help is appreciated
