Stuck at M on reboot after root

[kxkid]

So I rooted my Dx today using z4root and was wondering where to go from here. I have downloaded root tools and played with that. I am looking at changing my notification bar getting rid of the vzw header and other things. Thanks. Oh and I am thinking it might be helpful letting you know I have a Mac, most everything I have seen is for evil windows users.

Now I need help bad. I just changed my font and boot animation like I have before using root tools and now that I changed the boot animation to jurassic park all I get is the M when I turn it back on. I have access to a windows running xp. I need help please. I read on here that my phone is not bricked just that I more than likely lost root. Once again I ask for your help thanks.

oh and when it turns on to the m it vibrates for a millisecond

I think I know why it is stuck at M. I looked in the jurassic park folder in the root tools file and it did not have a bootanimation.zip file like the other had.
