Whatpulse keeps me logging off

I am having the following problem: My Whatpulse keeps me logging off.

I am using Whatpulse 2.8.4 (latest download), Windows 10 x64, WinPcap 4.1.3. I am using my Windows profile as administrator as I do Whatpulse. When I log on it redirects me to the website (I log on) and select the computer which I’d like to pulse on. It recognizes it’s settings and it shows me the logging in on the client. There I get the question if I’d like to keep the previous client settings. Whatever I choose, the client disappears (it seems it’s restarting) and I am logged out again. The only thing which works is the Geek screen, which seems to be working fine. (It counts everything).

Then I tried making a ‘new computer’, re-installing Whatpulse (even tried to downgrade), WinpCap, but nothing works. I’m not using VMware nor Anti-Virus/Internet-Security software, except those in the OS.

I have copied the app.log (didn’t inlcuded it). Is there anything which I can do to get this tool working again?

Isn’t there anyone who can help out?
