could you explain to the fine folks here at GS how the prefs get hosed up every time Cubase gets an update? Curious as to why this is the solution all the time.
That is a very good question, to be honest, I am not 100% sure, you don't have to delete the preferences all the time, and actually in most cases you do not need to delete the whole content of the preferences folder.
It actually depends on what the issue is; E.g. If some of your plug-ins are not being loaded, probably you should only have to delete the vst2xblacklist.xml file.
Some times it is just simpler and easier to delete the whole folder than search for the file that is causing the problem.
If you have installed a major upgrade (E.g. Cubase 6 to Cubase 7) Cubase 7 will import the Cubase 6 preferences which obviously can cause issues do to the changes on some features or behaviours of the new software.
That is why we also recommend to delete the preferences of both versions.
I will ask the developers and see if I can get you a more detailed answer about this
