Good enough. You have reverted to the first version linked above.
There's no mandate to update. The latest can always be test driven, even if unlicensed, to see how it performs.
For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee is required in order to register the newest. Retain your old install file and registration info. If there's an issue, you can always revert.
