I experience the same problem with missing sounds. Seems to be a stock SH5 problem.
Recovering from a hard drive failure. One of my WD Raptors that's in a 3 X RAID0 died last night. Since it being a RAID0 everything was lost. I had backups saved to my Windows Home Server so I'm now restoring my system back to 'normal'. Hopefully I can be back to modding here in a short while
This is my first WD Raptor to fail. And the sad part is it's less than 2 months old and is their 'Enterprise Storage' series one.....yeah right, Enterprise storage reliability my @ss.
