I was using Zdestop's earlier build -1083 and was able to connect to my Yahoo accounts (although I did not have Yahoo mail plus accounts). But then I started having problems with the desktop (it was not starting up) and I uninstalled it and installed the new desktop build (Apr 20).
Now I am not able to connect to my Yahoo accounts anymore. The desktop says I need Yahoo plus account. Was this a bug in Zdesktop's earlier version ?
