Corel Paint Shop Pro X patches and updates may help with your problem.
You <font color="red">MUST</font> install them if needed in order i.e. 10.01 first, then 10.02 & 10.03 in the respective language choice.
I see you have hopefully solved your problem but checking the version and updating won't do any harm.
