[WriteLog] Registration key expired or invalid?????

Fri Apr 24 18:56:12 PDT 2009

I downloaded V10.69 (full) in December to run on a new pc -- 
one w/o a serial port. I installed a USB-Serial adapter, 
but never was able to get Writelog to communicate with the 
rig, an FT-1000/D. I tried several times, but finally gave 
up and reverted to my old pc with a "real" COM port and my 
older version or WriteLog.
I uninstalled WriteLog V10.69 and the driver for the 
USB-Serial adapter and let my new pc sit for a couple of 
months.
Today I re-installed the USB-Serial adapter driver (it looks 
good) and tried to do a clean install of V10.69 from the 
original download from K5DJ. It unzipped OK, but would not 
accept the registration key I was given in December, which 
had previously worked OK. I received the following message:
"The registration key you have entered is either expired or 
invalid."
What's wrong, and how do I fix it?
Thanks,
