No callouts/TCAS warnings Etc

Following a FSX hangs computer repair shop had to re-install FSX and I was able to reload and activate MD-11.  Systems up and running but have no pilot call-outs e.g.: V1, V2 rotate, TCAS warnings, and other instrument clicks etc. but have throttle noise.

However when loading FSX I get a Warning message:

Flight Sims has detected a problem with 3rd party software program (add-on)

Name: PMDG Sounds Dynamic Link Library

Version 10.0.61355-62

Company PMDG

File PMDG\DLL's\PMDG SOUNDS.dll

Click yes to install software results in (FSX fatal error) and shuts down FSX 

Click no to install software will start FSX and able to run normal ops except for errors above

Any assistance please
