Important - Reupdate your unit!

[Tim Wessman]

In the edit->prefereces menu, what does it say as your "working folder"? Mine says something like: C:/Users/Tim Wessman/Documents/HP Connectivity Kit. You could manually download from http://ftp.hp.com/pub/calculators/Prime and unzip the firmware file into the "Firmware" directory. (ex:Documents/HP Connectivity Kit/Firmware)

Did the update check work for you before? Or has it never downloaded anything? It is possible the error message is just wrong and the network is actually at fault and not letting a direct connection through.
