Cheat Engine

[AlphaFire]

Hello Cheat Engine community, I have a problem with Cheat Engine that recently occurred. Whenever i try using speed hack it gives me these 2 errors:
- Failure determining what realgettickcount means
-Failure enabling speed hack Dll injection failed. Failed to allocate memory.
I'v tried using forcedinjection it did not work. When I inject it Cheat Engine stops working a.k.a. crashes. I'v been looking all over the post here trying to find my problem but I didn't. I found some files that Dark Byte posted and he said if you can speed hack these it's good. I was surprised when Cheat Engine was able to but it still doesn't work on downloaded programs and on Google. I tried using Cheat Engine 6.4 because I first got the issue on 6.5 but no use.
