My Monero wallet shows 0 XMR. I'm trying to recover it by restoring it from the GUI. After inputting my address and keys, the right arrow is greyed out so I'm unable to get to the next screen to continue my wallet restore. It happens on both options--"restore from seed" and "restore from keys". Does anyone know why? I don't know the restore height but that says it's optional anyway. I'm using the Windows 64 bit version 0.11.1.0 Helium Hydra.
