My PSP7 has been freezing and crashing 4 or 5 times a day. Can I reinstall the program over the current one to fix a problem? If I uninstall it, will I lose all of my tubes, gradients, plug ins, etc. that I have? Do I have to move them elsewhere? Will the uninstall recognize that they are in psp formats and remove them? HELP I hate when this thing doesn't work right. I have plenty of memory and use Windows XP home.
