I am having problems with Verichat on my 7520 too. It installs and runs great for a few hours. Then it logs me off and I can't log back in. Either I get Could Not Find a Service Book Entry (not true, I had 3 service books sent to me yesterday) or, No Connection or Max Connections Opened. I have v.1.92. I uninstalled and tried 1.91 to see if it made a difference and it hasn't. customer support keeps sending me v. 1.92. Now I'm trying Webmessenger. It's working fine but I really liked the Verichat layout better.
