ICX ERC 20 Tokens stuck in MEW

I’ve totally slept on the swap and have a nearly 9000 ICX tokens in my MEW/TREZOR. I created a ICONex wallet with an 0x address but whenever I try to move the ICX tokens over from MEW to ICONex, it gives me an error.

I do have my 24 word seed phrase but I’m stuck at the next step. Is there anyone with experience getting this transferred over to the ICONex wallet so I can start the manual swap? I am willing to pay for technical help at this point as I’m stuck after days of trying to figure this out.
