Yes, but you should also make sure you are running the latest version of Form Wizard Pro. Both mojoPortal core and Form Wizard Pro were recently updated to use the new version of AjaxControl toolkit therefore the latest version of Form Wizard Pro is only compatible with the latest version of mojoPortal and the latest version of mojoPortal is only compatible with the latest version of Form Wizard Pro. To be compatible they have to depend on the same version of AjaxControlToolkit, so whenver we update to a newer version of the toolkit in mojoPortal we always release a compatibility update for From Wizard Pro.
I don't see any purchase history on the account you are posting with here in the forums, to get the latest Form Wizard Pro, you'll need to login as the user who purchased it, then you can download the latest version from the order history tab under "My Account".
I'm not sure what version of mojoPortal or Form Wizard you are currently running but the error indicates they are not compatible because they depend on different versions of AjaxControlToolkit.
The link you posted for server information is a protected page, only members of allowed roles on your site can visit that page ie admins.
You can also find information about system requirements and release history of Form Wizard Pro on the Form Wizard Pro product page.
Hope that helps,
