Same issue - Comcast not helping at all
I am having the same issue as the original poster. I have contacted comcast three times with absolutely no success. Is there a solution to this zimba problem? If not, it is bye-bye comcast and hello Verizon.
Solution that worked for me...
Think I got it..., well at least the issues went away. You need to definely delete ALL of your cookies and history. I use CCleaner and had certain cookies of websites I visit often "protected" from being deleted (banking sites, Email sites, etc). Once I completely cleaned out everything in the temporary internet folders, including all cookies, restored my IE 8 to default settings, rebooted the computer and logged on again, the ZmMsgController error went away and there were no "problem loading page" errors. I could again open / forward emails sent to my comcast account.
