How to update CWM Galaxy S3 I747M With Rogers

[Sdvsraw]

Hi, I am very confused because when I try to install the Cyangenmod 10 ROM I get a Status 7 error. So I researched and found out I need to update CWM, But I have no clue on how to do this, I tried to use ROM Manager, but I could not find my device listed there. Am I allowed to flash CWM with a newer version, or will it brick my phone?
