aBUGSworstnightmare,
The additional details help. I use the J-Link support v0.1.0.4 in my CCSv5.5 and my LM4F232H5QD evaluation kit (a device identical to a TM4C123GH6PGE) and it works fine. My OS is Windows 7 64-bit.
I also updated the page to reflect the new device families and removed/re-wrote some confusing points. Thanks for pointing those out.
Cheers,
Rafael
