Yes, would love to know if it was a case of just needing to do another rebuild or something similar. I haven't experienced someone with that particular sets of problems - usually when a new PAK cannot be accessed it's due to not having installed the required patch, not having done a rebuild, in the event of a split install having installed them to the wrong drive, or the program wasn't closed during the install process (running the installers with it closed is what you would want to do). There's also the fact that you can technically view styles you don't have installed, so sometimes people have the filters set to show what's not actually present, but then N/A would show up on the RealTrack spots.

These symptoms sound similar to when someone with a Pro or MegaPAK chooses a style in the StylePicker they don't actually have the RealTracks for and load it in, and they don't hear it playing back, but there are normally messages about content not being found, and a rebuild resolves this most of the time. So the fact you didn't get playback or error messages is interesting. The only other thing that spawns to mind is an audio driver setup issue - but that wouldn't impact one specific Style set and would impact anything you'd load into the program.

At any rate, I would be curious what your resolution was incase someone else has a similar issue, and hopefully for those having not the exact same issue but a similar one may be able to take what I said above as potential things to try and resolve their own issue with Style PAKs not loading as expected.

Cheers,
