Dave this was discussed in a prior post on this forum. Do a search and you can find it. If my memory serves me right I am not sure if a solution has been found yet. You may have to uncheck the e-file conversion error checking box and see if you can e-file it and if it'll be accepted.. if there is no solution and there is no software update and then the return is rejected, then I guess your only option may be to ask client if he or she wants to mail it...just my opinion..
