Cheat Engine

Ok I have no problems with most of my dll! It injects and ejects from the game with no problem. Code caves are initialized correctly everything seems to work fine! if I access my codecave with a simple call instead of a jmp, and use a ret to return it works perfectly. However if i try to do a jmp and then a jmp back it immediately crashes the game upon execution of the returning jmp. My problem is that when it writes my code to the codecave and I look at it in Cheat Engine the jmp back looks like this "jmp dword ptr ds:[00484766]" and the game crashes the momment it tries to execute the jmp. however if i use cheat engine to re-write the jmp so it looks like so "jmp 00484766" it works perfectly. Anyone have any ideas how I might be able to fix this issue? Is there a different way of writing the jmp in the asm block that will write it in a way it will look like "jmp 00484766"?

You're adding '5' to the address of your variable (&Addy_GodMode+5), and then trying to jump to the value of that address. Instead of adding '5' to '0x00484761', and jumping to '0x00484766'.

Thank you for your help, and forgive me if im wrong but if that was the case then why would cheat engine show "jmp dword ptr ds:[00484766]" with the correct address of 00484766?

Furthermore if doing this is incorrect!

Remove __declspec(naked)

Thanks both for your help! I changed the code to that of what sponge suggested and that did the trick! Removing the __declspec(naked) had no effect one way or the other however, but thanks for the suggestion none the less.
