5'RACE problem

Hi, I am encountering a problem trying to deduce the 5' end sequence 
of a parainfluenze virus.  I have tried the Clonetech kit and didn't 
obtained a good result.  Then I checked the published sequence of PIV 
and found that there might be some secondary sturctures that could 
interfere with my RT reaction.  I have also tried the T4 RNA ligase 
method with a short piece of DNA oligo (I am still waiting on my RNA 
oligo) but it didn't work possibly due to the low efficiency of the 
RNA ligase working with a DNA oligo.  

So my question is that has anybody out there who can give me some 
pointer on how they did it???  Or some information on where I could 
find some good literature???  Thanks 

Kevin
