Does Truecrypt limits the number of standard volumes inside an outer volume when creating an hidden volume

Question

I´ve been trying to use Truecrypt as to create 3 standard encrypted volumes/containers and an hidden volume, all 4 inside a single outer volume. When using the Truecrypt wizard I and selecting the Hidden Volume option, I can then create the outer volume, the 2 first standard volumes but when I am creating the third one (just before creating the hidden volume) it just fails at about 75% of the formatting. The same error always appears on the screen telling me that the volume (the third one that I am intenting to create) is busy. I have restarted my computer and tried it many times but without any success, am i trying to do something which is not possible or is there another better way to do it?
