I am new at this posting and don't know how to post my thanks to Linc Davis, as I tried this and deleting the RSS folder and the problem is solved.
Good that you want to show appreciation. Unfortunately you cannot thank Linc through a post placed on another thread. Only an answer to your own question can be marked with a star.
To do that, click on the star that is within the post that answers your question and it will register to the credit of the person who replied.
