How did you buy the license?
You need to contact a reseller in your area. You can find a list of resellers on the sambapos.com website. Also you need to update to latest version by downloading it from same site. License price is not $99 anymore it will depend on the reseller and services they offer.
If you have trouble contacting a reseller in your area you can PM me and I can help you get one. There are a few of us on here that are resellers but it’s best to contact one in your area first.
