Convolution Reverb help!

I'm developing a convolution reverb in Simulink by FFT'ing both input signals (Input from mic and recorded impulse response), then convolving them with each other in the frequency domain, and applying an IFFT before sending it to a speaker output. However, no matter how much i've tried, i only get noise out of it. I was wondering if someone could help me.
I've also tried to just convolve the signals in the time domain but i get the same result.
Any kind of thoughts or pointers would be much appreciated.
Thank you.

Felipe,
How are you computing the convolution? Please show us the code that you're using.

How much energy is there in the tail of your impulse response? If there is lots of late reverb, then the result is going to sound an awful lot like noise. What happens if you cut the duration of your impulse response (IR) down to only include about 50 ms of reverb?
