Photoshop CS Issue

[cH1ooo]

Hey guys, I know Photoshop CS is many years old, but my office still uses it.
Recently I was testing some Photoshop portable edition on my workstation, when I messed up with the license. Now instead of showing the actual license, it just shows me the 1's...

Any way to fix u the sucker... Please help needed before the IT finds out...

TIA.

this is for cs3 but also applies to previous products, some file locations might be changed, plus u will need the original serial


1) First off, delete C:\Program Files\Common Files\Adobe\Adobe PCD\cache\cache.db

2) Then run any of the CS3 programs. Click Accept to continue, then enter your serial that used to work. BEFORE clicking next, you'll notice that you have a NEW cache.db file in C:\Program Files\Common Files\Adobe\Adobe PCD\cache

3) Right click the file, go to properties and make it READ ONLY, and then click next on CS3 after entering your key.

4) Next, after you get to the register software screen.

Click "Register Later"

5) Now it should be working, technically speaking that is, but you're not done yet.

The register screen should have popped up again. This time, remove the check for "Read Only" from that new cache.db file and select "Do Not Register" from the the top of the register software menu.

6) Now, as soon as you click continue, make the cache.db file read only again, and LEAVE IT THAT WAY to prevent a possible reoccurrence or Adobe trying to send the patch through again disguised as an "update".

Remember that if you need to reinstall the serials of any CS3 product which was working prior to the creation since you have created a new cache.db file you must temporarily uncheck the ?read only? properties box for the cache.db.

Then after inserting the serials and reactivating them close the program and then recheck the box.

Thanx; That works great on CS3 (i tried it at home), but at work in CS it didn't work.
I get this error:
"Could not complete your request because of missing of invalid personalization information"

I wonder if i can find a CS installer, and try to install it again. The problem is I don't wanna go to IT for that or they'll find out "what I did last summer..."
