Installed bootmii and now it wont boot

I installed bootmii as boot2 and all went fine, however when i powered off and turned on the drive flashed once and thats it. I am running menu 4 and preloader 0.29. I have tried removing the sd card but i still get the black screen and the single drive flash. Any help would be much appreciated,

Try booting into Preloader and then going to the Homebrew Channel and reinstalling/uninstalling BootMii.

Thanks for the reply but I tried loading preloader as well by holding reset but still just a black screen, it was deffinatly working as i loaded it just before installing bootmii

This sounds bad, you should report this to Team Twiizers, because there may be a major problem with BootMii.
