... your log is not complete, it should end with :
------- END log session ------------------
There is a 5000 characters limit per post, so please repost your log, but first delete everything related to FMs in it (too long and not relevant), most of the time it is the last part of the log that tells us where the big errors are ....
Then you still have lots and lots of errors, in different domains, but for sounds you have errors like :

... and I don't know where the "custom" comes from,
not from UV3 I think ... ???
I believe your install is all messed up, and it looks like you have another sound mod ...
May be you should reinstall from scratch and follow Bravo's instructions to the letter ...
Do you have these two folders
at the root of your game ?:
@sfs MOUNT tigersounds_1.sfs
@sfs MOUNT tigersounds_2.sfs
