This thread is tagged as being for cpg1.4.x. In my book, this includes cpg1.4.25 as well as cpg1.4.3819. So yes, this mod is designed to be used with any version of the cpg1.4.x series, and this includes cpg1.4.25.
We can't tell for sure, as it's simply beyond the scope of this board to test each available mod or hack with each new maintenance release. Why don't you try it for us: apply the mod and let us know if it worked for you or not. This would be a good way to give something back to the community. Taking into account your negative record on this forum it's about time for you to become a giver instead of being a taker constantly. Don't come up with lame excuses like "I'm not a coder" - you don't need to be a coder to apply this mod, test if it works and post feedback here in this thread. Nobody has been born as a coder - you live and learn.
Anyway, I can see what your issue is: this mod suggests to replace one of coppermine's files with a modified file that is based on an outdated version of coppermine, which can be a bad idea in terms of security and stability. The instructions of this mod never should have been put the way they are. I will try to make that up and post instructions that should work (see next posting).
