Jungle Flasher causing Net Framework error

When I try to open JungleFlasher I get the error - Unhandled exception has occurred in your application. Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I started getting this error after a bad flash. I was trying out a dvd key on a 8 series lite on drive when it froze up. Now the lite on drive is not working and probably needs to be reflashed.

I'm trying to seek the best steps on how I can troubleshoot this as it's pretty much over my head atm. I'm going through the search and trying to find similar topics so anything points would be great.

I do have the key dumps and the drive has been flashed before. I was only testing another systems drive key when the flash didn't go through.

I saw some posts about how the via 6421 might cause some freeze ups, I'm not sure if that pertains to me.

I also do not have a connectivity kit and was wondering if I could use another 360 to power it on and off or will I need to get one to troubleshoot this. If i do need one could someone please recommend one to get.

Thanks in advance and as you can probably tell a newb freaking out. =)
