Just to update on this problem.buksida wrote:Your existing profiles should all be there, Thunderbird doesn't delete them - it should just be a case of importing them into the new version:

Thanks a lot for the info Buksi.
I looked up the sites you mentioned and I just couldn't get my head around where to find my profile and then export it or relocate it.
Then I stumbled across a piece of freeware called MozBackup.
It's a very small program and will find your profile in Thunderbird or Firefox, compress it to a single file and you can then import it into a new program or computer.
Makes the whole thing child's play!!
