after reading, reading...and yet more reading...discovered I am not the only one with the current problem (screen going black on all homebrew apps) apparently the IOS36-64-v1042.wad is an old file and seems to do this on newer systems, and without proper nand backup, I cant restore...im on my way in a bit to do an exchange (after deleting all i could with what i had available to me). Thank you to all who put in their input...much appreciated!
