Help with ReActPSN 2.23 for Rogero 4.30 v2.03

I've already been on tutorials section.

1. activated my ps3 in account management, downloaded Max Payne 3 Gorilla Warfare Pack and got act.dat in my profile's exdata.
2. signed out of PSN and disabled internet
3. created and logged in "aa" account in xmb, and installed ReActPSN 2.23
4. made sure that USB/exdata contains rap files, and put it on right USB port nearer the disc tray

* When I ran ReActPSN, it just returned me in XMB with no message about not properly shutting down the ps3.
* Also, the app's name changed to:
ReActPSN 1.10
Unknown CFW!
* The "aa" account is still named "aa." It was not changed to reactpsn.
* I didn't find act.dat and act.key in aa's exdata folder.

I already followed what others did, but it didn't work for me.
I'm on Rogero CFW 4.30 v2.03.
My PS3 Model is CECH-2512B.
Please help.
