Starcraft 2 trainer doesn't work

[daikaio]

So I did what you asked for, and here's what I got:

I started the game and pressed num 0 : same results as before, both the audio and SC was not found messages.
I started a new campaign and it didn't worked either.

I then loaded different savegames from different versions and their respective trainers.
For saves with the version v1.4.1.19776 and v1.4.2.20141 I got the same errors (each trainer still had the green game status).
But for a load from v1.3.6.19269 it works without a problem. Only thing is that I can't continue the campaign, finishing the mission brings me back to the login screen.

I'll try a fresh new install and see if this fixes anything. I'll let you know how it turned out.
