The problem with this system is that it keeps wanting me to donate after I have already donated.

For me, the download starts before I am prompted to donate. Does the download not start at all for you?

After several attempts and navigating through several links, I got the download to work and installed the latest version. This all started with a prompt to download and install from my older version of TB. Before then, all went very smoothly, but this time, all Hell broke loose. After the first download and installation were completed, any new messages were created in the far right of the compose window.

Now, all seems well, and I am holding my breath. I hate webmail.
