No VST support after app store purchase

The application on the page appears to be 4.55 while on my mac it is 4.54 and still asking for an update. After an update it is again 4.55 and asks for an update. There is no VST support in this version of app which was installed from the mac app store while VST support was the main reason why I purchased this application. No support reply from the developers page.
