Take Dangerfreak's advice and report back.
Please mention your PC's specs: GPU/CPU/RAM and what version of VP is being used. Look at the bottom-left corner of the window.
Test the latest 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 will be required in order to register the newest. Retain your old install file and registration info.
