Does-Monthly-subscription-include-extensions-at-no-cost

No, but you can just try out the free 14 day trial, which will let you use all the extensions. Also, if you connect your WL.com user name (select Help/Download my License) the free trial period extends to 30 days.

I did try to do that but tells me I don't have a valid license to download. This lead me to think maybe I could do monthly for a month or two while I try it out.

Update: Now it insists I login and then tells me I don't have a valid license and shuts down.

Thanks,
