You have probably tried to beam Data Pro from one handheld to another using the Beam menu option on the Home launcher screen. This option beams the Data Pro program file only. To beam the other necessary files, you need a beaming utility such as Filez, available from www.palmgear.com, on the sending Palm OS device.

Install Filez, and then beam the following files to the receiving device:
Data Pro
DPsLkUp
DPStrings
Match Pro
MathLib

For Dana users, in addition to the previous five files, you will need to beam the following:
UsbBusDriver.PRC
vUSBLabProDriver.PRC
vUSBPrintDriver.PRC
