Thunderbird will not launch after online update to 1.5.0.7
Got a notification today to upgrade to the latest version of Thunderbird 1.5.0.7. The update downloaded and then crashed while installing on the next launch. Now when I try to launch Portable Thunderbird the process runs for about 5-10 seconds and then just disappears, no error messages or anything. Renaming my thunderbird profile and trying to launch did not make any difference either.
