Hi Vince:
Welcome to our Tech Support Forum. Sorry you are having trouble with the Silver Creek Collector outing.
Your content-error.txt indicate that the Jumping Brown Trout is either missing from your main RWFF fish folder, or the file is corrupt(very unlikely but possible). Please check and see if the Jumping Brown Trout is in your fish folder first. Go to your main RWFF folder and open the "fish" folder, and see if the Jumping Brown Trout is there.
The "Silver Creek Collector Edition" was uploaded with all the necessary fish files. Sometimes these don't get copied and pasted into the main RWFF fish folder and this will cause errors.
Please come back and let us know if you have the problem resolved. Good luck and good fishing.
Regards,
Stanley
