Local folders not transferred (import)

I transferred the entire eM folder from my PC to my laptop as described was in your help page but the local folders were not transferred properly. The folder are there and the email appear to be there but they are all empty. I have the headline from each email but no content in any of them.

Hi Henrik,
do you still have the old working database in your PC? Maybe there was some data corrupted through the transfer. Did you just move the whole folder or did you save your data through the Backup function and used the File>Restore option in the new computer?
