(adsbygoogle = window.adsbygoogle || []).push({}); im running a rebug 4.21 with updated rebug tool that spoofs me to 4.41... im connected to target manager, im on DEX, when i launch seb's tool i get an error "object reference not set to an instance of an object" or something like that any fixes??

Try to Attach via the Target Manager. If it doesn´t work you know why
Ist not the tool, ist your PS3

attach only when u are on the game or turn off ps3 and pc and try again

make sure you have a debug eboot on?
