Transferring email to Windows 7

I already have Thunderbird Profile folder backed up to a USB hard drive, and keep it backed up. I tried the Import option, but it only offers importing Eudora or Outlook. But even selecting one of these, it did nothing. I tried creating a new email address in the new Thunderbird programme, but it would not accept it, even though all the settings were correct. I have deleted everything (apart from my back up folder), so the computer is cleared of Thunderbird now. I did try earlier copying the Profile folder to the right location, and then installed Thunderbird, but that did not work either.

I wasn't clear about that.

I am desperate, I have tried Mozilla help but they don't answer. My new computer says "Your Thunderbird profile cannot be loaded it may be missing or inaccessible"

The profiles folder IS loaded, I copied it into C:\Users\Faith\AppData\Local\Thunderbird , then restarted the computer, but it still comes up with the same message. I deleted the TBird program, rebooted the computer and reinstalled it, still the same message. I tried the Moz back up, and did a back up, but could not find the file or folder it produced anywhere on my computer. So I resorted to copying the Thunderbird folder containing the Profiles etc onto an external hard drive and dragged it across into the path above. Don't know what else I can do now, except look at my nice new computer and can't get my email onto it. The thunderbird program won't even open, it just comes up with the message above."Your Thunderbird profile cannot be loaded it may be missing or inaccessible"

Does it run without this error in a new Windows account (without transferring anything from your backup)? It should create a new profile then, if there is none. From that point on, try building it up.

I deleted the programme and the profile, reinstalled Thunderbird after rebooting the computer, but it still won't open.

The fact you "copied it" is a clue. Not a good one but tells me you didn't try the Mozbackup and restore.

I see Kees has a good idea. Try that too.

I did a Moz backup, but if it make a backup folder or file, its not on the computer, I searched everything to try and find it.

Many folk have trouble finding their files. At least we know there is hope. That is, you have Kees idea and Mozbackup still.

I started from scratch again, re-downloaded Mozbackup, did the backup and found the file. I don't think it could have worked the first time. Installed the mozbak thing on new computer and did a restore, and everything loaded, one or two of the folders are empty, but not important ones, so I shall have to make do with that. Thanks for all your help, I do struggle, I guess its my age, I was born well before WW2 began ! so started on computers a bit late in the day, but intend to persevere ! Thanks again for your patience and help.

I followed the link, and read the posts, it seems most on there had trouble moving their Thunderbird Mail. I tried the back up, but can't find the back up file/folder, it gives no clue where its filed when it does the back up !!
One suggestion is to save the ________.slt file. I don't have any .slt files ! I do not want to go back to Outlook, I don't have all the options I have in Tbird, but it certainly is the most simple matter to transfer the mail folders.
So am still wondering how to get my mail into the new computer.
