The title says it all , The new version doesn't work on my pc so I tough about installing the older one (before this version) So can anyone help me by telling what version was the last CC and Can I Download it somwere?

You can download thr next oldest version here.

If that doesn't work (and even if it does work): Have you tried yet to start CC via the directx.bat file? (CC has a default on OpenGL) And does anything happen at all when you try to start CC?

I tried everything on the new CC but it simply wont work so ... I have to play the old version.

Open the new version of CC with the MS-DOS thingy DC added.
