Connectivity Kit

[Gilbert54]

I had the same issue and after an installation of the CK on an other computer I got the same problem.
I did indeed a factory reset and now it's OK.
Here is the procedure I followed ( I don't remember where I got it) :

"The following always resets the calculator to factory-new condition:
• Press and hold c, f, and o
• While holding them all down, poke a paperclip into the RESET hole in the back.
• When the diagnostic screen appears, release the c, f, and o keys.
• Press 4 (FLS Utility), then 3 (Format Disk C), then Enter. This will wipe the memory of the calculator to factory-new condition.
• When the blue OK appears, press Esc, then 9 (RESET).
• It usually ends with the initial setup, including swiping the tiny HP logo to the right with your finger, selecting the default language, and/or other stuff, depending on your hardware and firmware versions."
Hope it will resolve your trouble.
