On the Pro Pack (Legacy) page, it says the following:
This add on pack MAY work with the latest version of Store Locator Plus but is not guaranteed to work with versions beyond SLP 4.4.
Since I am on 4.7.4, I didn’t want to buy the Pro Pack and find out it didn’t work… We had purchased the Enhanced Map premium plug in which no longer works on our site so I didn’t want to purchase something else unless I knew that it works in our environment.
