Install the current release. 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.
If there's still an issue, go to OPTIONS | ADVANCED tab and, at the bottom, click the caret to the right of "default" and change it to "None (CPU only)."
