well im trying to find an address using an AoB but whenever i search for it i get error "nothing found"... what am i doing wrong?

EDIT:
ive found this AoB: 83 C0 0A 89 45 C0 89 75 0C 8B 87 84 04 00 00 99 now i tried to update it to a later version using memory view -> search -> find memory -> AoB and when i do that i just get an error "nothing found" i set to range of the address from 00000000 to FFFFFFFF yet no luck

P.S if it matters im trying to update this address from v0.62 to v0.83

Clearly what you are doing wrong is this :
Welcome to Cheat Engine ! Please edit your question to show [what you have tried so far](http://mattgemmell.com/what-have-you-tried/). You should include a [Minimal, Complete, and Verifiable example](http://stackoverflow.com/help/mcve) of the code that you are having problems with, then we can try to help with the specific problem. You should also read [How to Ask](http://stackoverflow.com/help/how-to-ask).

Post a screen of the memory region you made your AOBscan for.
Post your AOBscan signature.

Since you intend for us to read your mind and guess what went wrong out of 0 evidence I will suggest that you enable all memory regions for your aobScan :
Right click near the writable/copyonwrite/executable checkbox in the scan section of the main window and chose preset scan all memory (then all checkboxes should be squared (neither checked neither unchecked, the code word for it is "partiallychecked" in QT)



//Answer to edit (note that I have to use edit because it refuses a double post)

To make it easier for people to know when you've brought more information to your request it is better that you post a reply in place of an edit (because then there is a forum alert showing something new happened).

Note that the array you search for is
C0 0A 89 45 C0 89 75 0C 8B 87 84 04 00 00 99 83

whereas the array you claim to have found is
83 C0 0A 89 45 C0 89 75 0C 8B 87 84 04 00 00 99

Could you please provide a memory viewer screen of the bytes used for the signature ?
I am talking of the bytes from the "Bytes" column, in between address and opcode column from memory viewer.

thanks for your help!

whenever i paste\write the AoB the 83 just "stay" in his place and the rest of the code just pass it...

and this is a picture of the address+AoB from the version that does work:
i m g u r . c o m/a/yjeBE (again with the spaces..)

Try your AOB this way :

Have highlighted important options.
If that doesn't work though, I wouldn't be too surprised as those two screens you provided have different executable names.
If those exe are not compiled by the same company (ie most likely different compiler settings / IDE) using the same base source code, asm signature are a lot more likely to fail.

well i tried it with those settings yet no luck and about the source code.. well im sure that this game uses the same source code the name of the exe is because its a different private server but that game it self is based on the same code.. perhaps another way to find the address?
