What kind of problems? You should have stuck with HF4 as there are other nice fixes in there.
If you are referring to the sound issue, this is a simple fix which can take about 3 seconds to repair.
Install Audacity. Set the project (at the bottom) to 44200 Hz. Open the broken asset
Resave the .wav files.
Commit and you're done.
If it's the same sound for all the assets, fix one and copy the same sound to multiple files afterwards. I did that and repaired 30 passenger cars all at the same time.
