I recently purchased a GDL block from objectsonline.com. Much to my frustration, every time I try to load the block, I get the Duplicate parts error. Apparently, the four blocks I purchased all have the ID number of 36 zeroes - 36 zeroes. Is there any way to change the ID number? Is there a a simpler way to deal with this problem? I should also mention that the four files are all different with different file names. It's just the ID number that is the same.
