Failure, failure, failure!

I lay crumpled on the ground exhausted, in tears. I had worked long into the night, casting all the appropriate spells, using all the correct forms. I was able to get the necessary components for the spell (aka a brand new working mother board and power supply). I know the spell forms are correct, because I was able to feel the power flow through me, and made a tenuous start to the realms of the living (the computer booted up). But after that, everything went haywire. There was an unrealized shiled sent by the Keeper of the Underworld to block further efforts (it turns out my dvd player wouldn't open, I couldn't get the system repair dvd into it). Then, out of the blue, all the energies of my spell ceased (the same problem as before, the computer wouldn't power up at all). I am at wit's end. What am I to do? I can stand no longer to be trapped in this realm of shrouded fog. I must make it back to Caledon before Beltane!
