[chirp_users] chirp and windows 8

[LeonardKeepers]

hello group. i have a windows 8 laptop. just recently upgraded to 
windows 8.1. i want to do some program editing to my kenwood thf6a. 
chirp and the radio cannot talk to each other because chirp tells me it 
cannot find the com port. it worked okay until i upgraded to 8.1. the 
question is, do i have to put in a new driver so that chirp and the 
radio can communicate. thank you
Leonard
