Default ICS messaging freezes phone

I am using [rom][ics][ucld2] ●► embryo-2.1 ◄● 04/22/2012

My last rom(cannot remember the name) the ICS messaging app came pre-installed.

When I download and install it on my current rom it freezes my phone. I'm not sure if I have to make ICS messaging app the default or something? I am not even prompted to do so?

Any help would be appreciated
