How I can unlock this: It seems the auxiliary files folder are locked at "C' and it is impossible to erase o change that location into another Hard Drive e.g. "E" so Anyhow, I try to prepare a DvD I get the message " There is no enough space......" but I have not access to change the location on "preferences burn tab"......... DvD Arquitec Studio 3.0a. Yes I unistalled and reinstalled but nothing change.
