lighting and texture change after update?

Hello.

New to Unity, about a month now, and this is the first time I’ve gone through a version upgrade. When I opened up a game I had been working on I got a warning that it was created using an older version and I might need to reload the project. I clicked continue and opened the project and noticed two things.

First the one object in the game that had a normal map applied was missing it’s normal map. No problem, just reapplied it to the object. The more confusing thing is the lighting has a pinkish / purplish tint to it that it didn’t have before. I looked at the light but didn’t see anything odd. It is just the default lamp that I changed to a slight tan tint, and the inspector shows slight tan selected, but parts of the scene have this pinkish tint.

So I guess my questions would be, what does it mean by reload the scene, and how is it done, and what might be the cause of the tint.

Thanks in advance.

Another post was made in the New to Unity forum that has a picture of what is happening.
