I have a new Macbook Air and transfered my Photoshop CS4 over to it using a timemachine backup. I am now getting a message Photoshop error 150:30. I am out of the country and so can't do a reinstall and don't have a DVD drive anyway so can't reinstall off the disk. Is there any way to clear this error and allow me to put in my code?
Solution 2 has worked for me when I had this error restoring from Time Machine. I suggest trying this first.
