I have Photoshop CS2 installed on my MacBook, and I am using Mac OSX Version 10.6.8 My photoshop was working perfectly yesterday but today when I try to open files it comes up 'could not complete the open command because of a disk error' and also when I try to save, the same message appears. Please help, I really need to use Photoshop urgently! I installed updates this morning and restarted my mac, could this be what has caused it? Thank you
