forest Muggins

One day I had the bright Idea to explore beta grid, and downloaded the beta grid viewer, problem is now when using viewer 2 when i switch the grids back to the main grid, it will log me into the main grid I just see weird things like only objects under water, gray avatars, and even even avatars that are see thru. I Don't believe this is the 10,10,10 error. does anyone have a clue, and if your asking I am on A Mac
