Try destaining the gel with your methanol/acetic acid solution that you used 
to remove excess stain. Make sure that the gel is rehydrated as the methanol
tends to dry the acrylamide matrix and make it brittle. After this you may 
transfer to nitrocellulose using standard techniques.

I have had success directly transferring stained gels to nitrocellulose, the
stain will simply be washed out when you begine your probing procedures.
