After a trouble-free couple of years, WLM started constantly alerting me that my "server had unexpectedly terminated the connection".  I have repaired WLM from the control panel, and I've deleted my gmail account 2 or 3 times and added it back in, but to no avail, except that now it wants me to log in every time I open the program.  I never used a login for gmail--nobody else uses my computer.  Not only that, but it won't accept my gmail address and password.  I have Win7, 64-bit and a good internet connection that is not the problem.
