Incompatible Email Mesages

[joddle]

I have been using TB 2 for years now but having tried various upgrades I keep finding that after TB11 my messages saved with Mozbackup wont load properly. Well that's not quite true, they load OK but when I try and view them many simply display a blank screen. Its not that the messages are very old even - some only generated a year ago but all versions from TB12 onwards do the same thing. The same archive file loaded into any TB versions from 2 to 11 display fine. I simply can understand why most recent emails are OK and others just a little older are not - i.e all the most recent ones are OK but those further back don't work - it does not seem to be the format of the email but more something to do with their age - or perhaps the age of the TB version they were captured with. I have received some possible reasons for this but these do not seem to fit the actual situation I am seeing - so any more information needed please as to what is happening here.
