I received 50BTC back in 2010 from a friend of mine. The harddrive ended up getting severe platter damage. 7 years and $2700 later I was able to recover the wallet.dat file that shows it was last updated in 2011. I was running the bitcoin-0.3.18-win32 software. Today I dropped that old wallet.dat file in the latest bitcoin core software and cant get any of my transactions or balance to show. Where do I go from here to finish up recovering this old BTC? Any help would be greatly appreciated.
