If your phone is running Windows Mobile v.5 then you are in the same boat as me. I have not been able to get an answer as to when we can expect compatability with Windows Mobile 5 phones.
Logbook Pro PDA Companion will start and present the home page but when selecting any of the 8 selections, either via the screen or via the View selection, I get the PC Data Missing ERROR, Unable to locate Logbook Pro data from PC. Start then Close Logbook Pro on your PC to send data to the device automatically. Apparently the data is place in a different spot than where it is looking for it or the data is not getting transfered to the PDA. This is on the Cingular 8125 which, according to the latest newsletter because it will accept screen inputs, is supported. Any ideas as to what is happening??
