PACLED64 - Please help set multiple device IDs

[coldcoffeecup]

I have 2 UltimateIO boards, and I'm trying to set the IDs for each of them, such that I can use them in the LEDBlinky program. I am using the RGB LED modules from paradise arcade found here.

2 assumptions I'm making:
1) PACLED64 is the correct software to configure the UltimateIO boards' IDs
2) I'm able to use 2 UltimateIO boards at the same time. I've had no problem with the controls themselves, but I can't for the life of me get the LEDs to work coherently.

Issues:
1) When I run the PACLED software, some variations of the brightness and random settings work, ONLY when 1 board or the other is connected.
2) I believe the process I need to go through is to plug in a single board, set the ID, disconnect, plug in the next board, set ID. Then I can have both connected uniquely. The problem I'm having is that within the PACLED64 software, the buttons to set the device IDs are always grayed out, such that I can't click on them. I have no clue how I'm supposed to change the device ID.
3) Although at one point a few weeks ago I was able to upgrade the firmware, now when I try and upgrade the firmware the tool reports there is no device connected, or upgrade is complete (before I select the firmware file).
4) Within the PACLED64 software, no matter which device ID I select (bottom left corner) it shows an UltimateIO connected, which seems to make no sense... even when I change to different device IDs, it still lets me clear flash, turn on LEDs, etc.

I'm getting increasingly frustrated by the minute. Any help to get me started, and move on to using the LEDBlinky program would be VERY much appreciated! Thanks in advance.
