VVP and WxSolution

I have been using VVP for several years, and just recently have developed a problem with WxSolution communicating with VVP. I ran WxSoultion for at least 2 years with no problems at all. I have a vantage pro2 station, running windows xp with a serial data logger. I also run weatherlink and cumulus. They are communicating with VVP just fine, but WxSolution will connect, then after about 15 seconds display the red reception lost message at the top. I click on the status screen on VVP, and it says “sending loop x of 255”, with x being a number counting up until the lost reception screen appears. It then restarts at sending loop 1 of 255, and doesn’t do anything else. I can click to restart communications on the port for WxSolution in VVP, and it will reconnect, but only for about 15 seconds again. I have connected WxSolution directly to my com port and it works flawlessly. I have also tried only connecting WxSolution to VVP, with no other programs running, and it still stops communicating.

Here is the View Log information from WxSolution:

I have rolled back to earlier versions of VVP and WxSolution, but the same thing happens. I have also uninstalled and reinstalled both programs with no luck.

I am at a loss. Any suggestions would be greatly appreciated!
