I purchased a PODxt used from a music store this week. I was able to successfully register it at line6.com after making an account there. Per instructions I found on the site to upgrade the firmware, I downloaded and installed Line 6 Monkey on my Windows 7 SP1 computer. After I installed the drivers for the PODxt Monkey was able to see it. As you can see from the attached screen shot, Drivers, USB Firmware, Line 6 License Manager and Line 6 Monkey are installed with the latest versions. But Flash Memory has a question mark and the Update Selection button is grayed out. I also ran License Manager and authorized the PODxt and my computer.
Since the goal of all this was to upgrade the Flash Memory (firmware) to version 3.01 I'm pretty frustrated and would appreciate any help. Since I play guitar and bass I was very interested to read that if you have version 3.01 you can install the Bass Expansion Model Pack. I will probably do that later as it is $99. I only paid $99.99 for the PODxt so will take some time to get used to the basic functions with guitar before moving on to bass.
Thanks,
Don
