Starting Parameters Problem for PlateSolve2

I have suddenly hit a snag with PS2 which worked fine until now with SGP. Now it will not solve. Despite how I set the parameters, when it starts a plate solve, it sets the search area at 17100 X 17100 degrees - totally bogus. Then the Search Center is completely random and not related to the target starting parameters. It then tries to go through a solution but due to the center it is using it won’t find a match. Keeps trying though but it is essentially looking over the entire sky.

When I edit the degree X degree starting parameter for the area, the change is not retained. Any ideas on how I can fix that?
