Photoshop CS3 doesn't open jpg and psd anymore

Question

I use PSCS3 for one year without any problem.And now, when trying to open jpg or psd files I get this message:
"cannot open photoshop.exe because DLBCGF.DLL is absent"
When I click away this message a few (10 ) times, the file does open...?
I searched for this file and copied it into system 32 and another time into photoshop itself without any result.
A desinstallation and reïnstallation of PSCS3 didn't help.
Raw files do open without any problem.
Any help is more then welcome !

Answer 1

To explain: DLLs are a collection of executable code bits, but not necessarily a single file contains all bits and pieces for a given operation. Whenever a program requests a certain function from one DLL, this may mean that in turn that function may go on the lookout for another sub-function it needs. So if e.g. in your situation you open up a file, it will call up a specific piece of the printer driver, probably looking for color profile information/ color metrics. These snippets then might call another segment of a DLL, which contains either a settings panel to make adjustments or switch to another color profile, settings for paper size and rasterization, ink status monitor and whatnot. If you will, you could imagine it as a family of parents, children, brothers and sisters and even remote cousins who on their own can achieve nothing, but when combining their wits and individual strengths can give you a certain functionality.
