CS 5 keeps asking for serial number after every re-start
Hi, hope someone can help me with this.
I've been using Photoshop CS5.1 Extended for several years without any problems. But a few weeks ago, out of the blue (no major changes or new installations on my computer) it suddenly started asking for my serial number every time I'm starting the program. I can enter it and confirm it (it's valid and the registration is confirmed), but as soon as I shut down Photoshop and start it again -- I have to enter it again.
I have no idea what to do other than re-entering it every time. I've googled and found some posts saying I should rename some cache.db file, but that didn't work -- a new cache file popped up right after renaming it and the problem persisted.
Any help will be much appreciated.
I'm using Windows 8.1, and I have both the 64-Bit and the 32-Bit versions installed (used to work without any problems or complications). Serial number is valid and legal. Internet works fine to connect to the licensing server.
Thanks!
