hi im trying to update my treo 650 with

"Treo_650_Updater_1_20_LAP.exe" cuz i have 1.03 version but while doing the sync i kept getting the error message

there is Not enough memory space to install this update on ur device
please free 13806 kb on the device and run the updater again " error during installation

is is worth it or if i uninstall all is it gonna affect the treo
tks in advance
