We added stricter input checking and I forgot to consider that currency symbols can contain numbers. Until the next alpha, you can remove EMC2 by clicking "Debug" in the app menu, and then click "Show settings", then remove EMC2 from enabledCoins and save. Then restart HyperDEX and you should be able to login again.
