addon/plugin not showing up in WHMCS?

I have purchased "WHMCS MU Provisioning" through WPMUDEV, I have installed the modules correctly and re-installed via the directions multiple times but in the Addons/myaddons section of the whmcs software does not have it listed in there. The files are listed on my server /whmcs/modules/addons and /whmcs/modules/servers/whmcs_multisite. Please help in explaining what is needed to make this work?

Thanks,
