I've checked it and it works just fine.  I'm able to encrypt to it  
without any problems.

I'm afraid that doesn't leave you with a good answer, though.  I don't  
think it will help, but it's worth trying making a larger key, as I  
suggest above.  Aside from that, your bank or whoever you are  
communicating with needs to give you some more information about why  
this is failing.
