I have photoshop CS4 and CS5 that I got through doing an associates degree program. They've worked fine in the past, but recently they've started giving me a message when I try to use them that the licensing has stopped working and the error is 150:30. I don't understand why it's doing that because I did everything right when I installed them. And they seem to be okay when I restart my computer, but it's like I have to open them as soon as I start my computer or they won't work later and I can't keep restarting my computer. If anyone knows what's going on, please let me know how I can fix this.
