I need to fix my Humax PVR9200T!?

I have just installed the new software for the Humax PVR92000T (PGXTF 1.00.23) and now the player will not turn on and says 'Please, Wait ...' and this does not disapear. I cannot turn on or off the machine except for using the switch at the back of the machine. Please help as now not only can i not watch any recorded programmes but i now cannot watch anything at all!

Would love some advice,
JJ
