Strange problem with Homefront

[Bluloa]

Looking for some help with the game homefront.

So I purchased my copy of Homefront, I backed it up and applied the 3.55 CFW fix.

Ive spent a good few hours playing the game and I went online today using both Spoof 3.6 and **** PSN and it all worked perfect.

Now tonight I fancied another game and It wont work!!!

Well I say iy wont work, Ive discovered it wont work if I have my Internet enabled.

If I switch the Internet off It loads up and lets me play missions, but If I switch the Internet on to play online the game gives me a black screen with a No signal message on my TV.

I really dont understand what could be wrong as it was all working perfect, nothing has changed except for upgrading MM to the new version and yes I have tried using the previous version of MM.

Internet on - Black screen no boot up of the game.
Internet off - Game boots up perfect.

Any Ideas?

Thanks.

Well I finally figured it out.

I had some download content downloading from PSN and for some reason this was stopping me from playing online.

Oncer the dlc finished the game worked as normal.

Very Strange!
