Set Virtual Guitarist 2 content folder in Lion? / VG2 OSX 10

Unfortunately it doesn’t work for me on my new imac (3.4 GHz Intel Core i7)…

I did as suggested and entered the following text in the com.steinberg.Virtual Guitarist 2.plist file:

<?xml version="1.0" encoding="UTF-8"?> Data Path /Volumes/Promise RAID/Virtual Instruments/Virtual Guitarist 2 Content/

I saved the file, got lots of hope…but the VG2 application still cannot find the VG2 content. Did I do something wrong ?
