Incredimail How do I return to version 2.0

Hi to all users out there from sunny spain
I have upgraded to the latest version of Incredimail 2.5 and wanted to know if other users were suffering the same problems as myself.

Several changes seem to have taken place.
1.No back up facility as previous versons without subscribing.
Note other forums state that paying for an annual subscription doesn't guarantee getting answers from the author to any problems
2, Whilst typing a new message , I sometimes gett¡ multiple copies in the draft folder
Likewise multiple copies in the deleted folder of the same email in various stages of completion!!
Finally some messages go into the outbox when I press send and then they stay there!!!
Any other members getting probs.
How do I return to version 2.0 (if available) without losing all my previously saved emails in various folders.
