I think this is the missing file (FCP_SMT_152_GASE_Acoustic_Studio_Kit.vstsound) that we need to have for Acoustic Agent to run. How can we get it? 
I think if you can find this file and place it here (C:\Users[windows user name]\AppData\Roaming\Steinberg\Content\Groove Agent\FCP_SMT_152_GASE_Acoustic_Studio_Kit.vstsound) then it should work.
