I am having exactly the same trouble and it looks to be the same as mine which is CnM H.264
I bought mine from CPC (FARNEL'S) THE O/S IS LINUX I set it up temp six months ago just to try it and now cannot get in just like you , there is plenty of help IF YOU CAN GET INTO THE SECOND SECTION but no help at all as yet to get past our problem If you know anyone who has a linux based computer they may be able to help but I have asked lots of "experts" and it seems to have got them beat
if you do have any success please let me know and I will do the same
I also understand if anyone has bought from Maplins they send there customers a program (though how they load it I have no idea) to rectify the problem so if you know any one who has bought this system from maplins you might borrow theres
