Boxifier has stopped working after saying it was "upgrading" for three Months

Hi, can I get some advice, please? Boxifier has stopped working after saying it was “upgrading” for three Months for 3 months and I don’t know how to restart It?
It also has a Note in the Taskbar saying _“Boxifier Need’s your Attention” ?_when I right click the Icon in the Taskbar Thanks for any Help you can give Daryl

Could you please try going to the Boxifier website, downloading the latest version and installing it that way?

Thank’s Christine, I guess I have to Pay to Upgrade? Not enough Use for That, Thanks for Your Help

No need to pay anything. Just download the latest version and install it. Always run the latest version of Boxifier in order to make sure it is compatible with the latest version of Dropbox.
