Getting: sfFTPLib not licensed.

I use the v1.5.991.24 but tried installing v 2.x - now after uninstalling v 2 I get this error???

I really wish to use the v 1.5 because I like the user interface much better.

I really don't appreciate many of the changes and I have been using SmartFTP for many years now. Many of the new additions makes a very nice program much more complicated to use.

The adress bar is very annoying for adding new ftp's with the same username / pass but with different ip's. - user , there should be an option to make it work like before with just the ip.

Well my complaint is about the sfFTPLib not licensed - is there anything to do about it?
