Okay, the download finally worked. Everything is fine when i load your games. Boat and Anchor are there.
I saved your treasure hunt savegame after loading it and attached it. Try if that helps.
If you still have your installer file make an MD5 check on it. If it's corrupt, redownload and install it. If it's okay, uninstall and reinstall it.
Please download and install Hashcheck
Then unzip and copy the attached MD5 File into the folder that contains the installers you downloaded from Telltale.
Finally just double click on the .md5 file for verification and tell us the results.
Green: File is okay.
Yellow: File is missing.
Read: File is corrupt.
