Can I brick my PS3 from reActPSN v2.26?

Hello,

I wanted to ask a question...
Can I brick my PS3 from reActPSN v2.26?
If yes, how?
What happens if I open reActPSN from my main account, or what happens if I open reActPSN from another account (not aa).

I want to know because I want to install PSN games and I'm afraid of bricking my PS3.

I'm on rogero 4.40 v1.03

Thank you in advance.
