I have been using SmartFTP for 159 days free as it is for my use only.

Today I got a message saying it is about to expire and to buy now or install the latest version. The thing is I have the latest version.

It says:

SmartFTP Expiration
This smartftp build is about to expire

Your SmartFTP build is about to expire. Please buy a license or update to the latest build to remove this expiration notice.

Can you help?
