UniBlu Powersuite making my game resolutions weird?

i installed the UniBlu powersuite yesterday and everything was running perfectly. this morning when i turned on my computer, i went to play some GTA san andreas and my screen was a lot smaller than usual (i have a wide screen monitor and it was cutting a quarter of the screen off from the left side and the right side). the game looked stretched out and when i went into the display settings to change resolution and set the game to "widescreen--on", it changed nothing and the game stayed the same. the same thing is true for when i went to play combat arms. any way to fix this? is it UniBlu's fault that this happened?
