express burn took over!

[mercgal]

I recently installed the 'free' version of express burn and unfortunately it has taken 'command' of any jpg's that are attached to my mail. I have Paint Shop Pro installed on my computer and have always had this as the default, but when I try to open the mail attachments, Express Burn automatically opens. It did the same with all the stored photo's I have on my computer, until I was able to designate Paint Shop Pro to open them. I am unable to find the solution for my mail attachments. I also noticed that Express Burn changed all my setting on my media player but I was able to correct this problem. Can anyone help? Thanks in advance.
