when you install paintshop pro it changes it to open all your files to open with it, all you have to do is what bach_m said at the beginning of the thread to open all your files in what you used to...(or right click>prperties> open with "lala thing"
this thread confused me a bit
but thats how you solve the problem i am thinking you're having. and dont get mad if this is not what you meant, this is what i understood from your thread.
