PSP Games/Apps refuse to connect to internet/network

Hey

I've upgraded to 5.50 GEN-D

and none of my apps (PSP KVM/PSPTUBE etc..)
as well my portable ops plus game will connect,
so im without multiplayer and silly videos

however.. psp's built in browser still easily connects
where as the other force into a loop of key info,connect,key info etc.

is there a recovery setting behind this?
i feel there is something simple behind this...as only booted games/apps fail where as the XMB broswer is fine

any help appreciated thanks

EDIT
OK,its a Gen-d bug.. fixed in 5.50 GEN-D2
hope this helps anyone else
