The operation can’t be completed because the item “iTunes Library Extras.itdb” is in use.

I am trying to transfer my iTunes from my PC to my new Mac. After reading through this forum a bit, I followed the instructions at: http://www.macworld.com/article/146958/2010/03/move_itunes_windows_mac.html

I backed up my PC's iTunes folder to an external drive after selecting to consolidate files, etc.

I connected the external drive to my Mac and did a copy and paste of the iTunes folder. I have not put any music into the iTunes on the Mac, so I just said Yes to overrite (it said there are 2 files that will be overwritten- I think they are apps I downloaded this weekenad i am fine to overwrite them). It starts to copy and then I get the error message: "The operation can’t be completed because the item “iTunes Library Extras.itdb” is in use." I verified that I do not have iTunes open on the Mac and made sure that when I backed up from PC, I did not have iTunes open there either.

Any ideas?

Thanks
