That won't change anything however. It's just an improved installer - it installs the same.
You're the second person to complain the latest update to Base has broken your database. Direct complaints/queries to TDF as they're the ones responsible and the only ones who can fix it. Build number changes shouldn't break functionality without very good reasons, so ask them what they've done, tell them what they've broken, and ask them to help you get your data accessible again. After all, there's no point having a database if it can't be accessed. Data is not a toy.
Having said all that, I've looked through the changelog and can see nothing relating particularly to base and nothing that looks as if it would affect a database. Have you checked the JRE is properly recognised, which is the last stage of the install and has to be done manually each time?
