Unhappy [Q] can't install bootloader or rom in twrp

TF201 rooted and unlocked.
Twrp v. 2.6.0.0.
Android version 4.2.1
Build - Energy rom March 28th, 2013 JP J0P40D.WW_epad - 10.6.

Twrp is not working. It does not recognize my internal storage or sdcard. I cannot install roms or restore or backup anything. If I try to wipe data I get failed with a list of missing items. Spent days reading and I am frustrated.
