How to Re-install Draftsight software corrupted due to Windows10 upgrade

Windows 10 recently upgraded on my Lenovo laptop and now when I open Draftsight project it opens fine but then drawing just zooms out and I cannot control zoom with scroll wheel or any other way. I've had other Windows upgrades in the past and this is first time this has happened. It appears I have other issues on my laptop with scrolling and the navigation panel as well with this recent Windows upgrade.

Can I simply uninstall current corrupted software and reinstall new version from website using my license info?

thanks,
