You're very welcome and speaking of welcome, welcome to the forum. Most common issues like this are thoroughly documented in posts or DIY articles. You should read those just to get a sense of what can and will go wrong with your car.

As to the OVP, it's a dirt simple task to replace. If you're good with a soldering iron, you may find that opening said relay will reveal cracked solder joints that can be re-soldered to yield a perfectly functional relay. Sadly, the OVP relay is not the only place where cracked solder joints wreak havoc on these cars.
