Audacity is not very good with VST's. It only supports some, and some make Audacity crash. Because of licensing restrictions, Audacity can not be distributed with VST support, so VST support is achieved through another little program called the VST Bridge. Also, the graphical interface for the plug-ins are not supported for the same reason, so Audacity uses a very basic GUI that looks similar to the interfaces for its built in effects and is just a bunch of sliders. Without the (often complex) VST graphical interface, these programs become near impossible to use. To use VST effects I think that you would be better to record using a proper VST host. On Windows you could try Waveosaur or Reaper.
