Ahh... If you highlight the the RealTracks folder, and do "Get Info..." again, at the bottom of the window you will see "Sharing and permissions" is your account name listed there ?

It should be there, and next to it (in the privilege column) it should say "read & write".
If not you should add your account, and make the permissions "read & write" then pull down the gear menu and select "apply to enclosed items". You will get a warning saying "are you sure ?" click OK and try BIAB again.

That should do it.
