Webassist claim that "Site Assist Pro" is a different beast, which is why they are charging previous Super Suite owners $$99.95 for the update.
If this is the case, then why is the current version of Super Suite the same price as my version. Especially considering it includes Site Assist Pro plus other extensions not included in my version, like CSS Menus that I paid extra for.
I guess previous purchasers of Super Suite are another source of revenue.
I have no objection to paying for an upgrade to a better and different product. but in this case I have no version of "Site Assist" that is CS4 compatible.
