Astro-Nautilus gameplay bugs (my keys only register in chat)

I recently started a normals game with some friends we loaded in quickly i was playing Nautilus in the top lane. once the minions came to lane i took w as my first ability and moved from under tower to the blue side river top bush. I tried to place a ward and noticed the game would not register my 4 key. i quickly returned to lane to avoid missing cs and when the enemy Teemo tried to auto me for an early trade i hit w to bring up my shield and noticed that the game would not register my w key. when i hit lvl 2 i took e as my second ability and i couldn't use it or my corrupting potion either. I tried to press to return to base but as my b key would not register i had to walk back. My enter key was the only one that would register and much to my frustration i discovered that all of my keys worked in chat. I told my team that i was gonna afk and try to logout and back in to see if that would fix it but it did not. I tried loging out and back in again to no avail. After this and feeling quite defeated i went and made a sandwich and watched the game. At first i thought we would lose, but our anny was quite fed and as the game neared the 35 minute mark, i bought a statik shiv a phantom dancer and some mobo boots. i was only lvl 2 with 4 cs but i figured i could at least keep waves of minions from taking unprotected towers. we eventually won no help from me my score was 0/0/4. Also the astro nautilus skin kept glitching and dropping his gold visor periodically even though my w would not register.
