Default [Q] Trying to restore recovery/OS but can't put any files on it!

I have an LG G2 D800 with Cyanogenmod on it right now, and Clockwork Mod for my recovery. When booting into CWM, it gives me these errors:

E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log

Also, when in the OS (in Cyanodenmod), when I plug it in, it won't let me drag any files onto it. The Google Play Store keeps on crashing too. What I want to do is just flash a new recovery, then wipe away CM and start it again. It's kind of hard right now though because I have no idea how I can get the files on my phone to do this, any help will be appreciated.
