Has anyone ever received the following deployment error message:

"MdxScript(MyDemoCube) (7, 8) The 'Measures' dimension contains more than one hierarchy, therefore the hierarchy must be explicitly specified."

Since I added a calculated measure to my cube I am no longer able to deploy it.
I have sent my project to someone else who was able to deploy it perfectly well (so there is no hierarchy conflict apparently), but I cannot do so on my machine. (I have encountered this problem with another project in which I attempted to create a calculated measure as well, and this was in a cube created in a class situation, where I followed instructions religiously!!!!) The syntax for my calculation is OK, I've checked it.
Thanks for any expertise you may have! I'm stumped....
