I am wondering if you can help me out with a problem I'm having, it's driving me nuts! I had dp5.13 and dp6.02 installed on my mac, and just yesterday put dp7 on it. The problem is that while loading up the default "new" project, dp7 tells me that the file was created in a later version of dp- so I tried removing the previous versions of dp (with appzapper once, manually another time) and followed the directions to remove this pretty common error by deleting the "auth" files from the system. I really looked everywhere and deleted every preference, template ecc from the hard drive.
Now, re installed dp7, re-authorized, but BAM! still not working. I really don't know any more solutions, if you guys had a similar situation, let me know

Thanks!!
