I have been using thunderbird as my default email client for about 2 years. Suddenly a few days ago, I am not able to receive email. It receive an error msg something to the tune of "pls enter password for this account" (Sorry at another computer posting this msg , so dont have screen shot to provide). I have not changed any passwords. Enter my password and keep getting the same error message. I tried to look around online for assistance. The only thing I can thing I found which might be related it something about how thunderbird and McAFee Virus Scan dont like each other. Earlier in the day, I was trying to download a free version Of McAFee Family Protection to use as Parental Control with my Time Warner Cable/Internet account. Ultimately I Was UNABLE to downlad McAfee (error message about frame too small??). But it was right after that I noticed I was unable to receive messages on thunderbird. I can send, but not receive. Can anyone out there advise what to do?
