My hard drive crashed with my backup odarc file that I did not move to my backup! I do have the latest player package file. This was created in 3.6.1. Is there a way to rebuild the library from a player package? Please say yes...
I had a similar thing happen years ago, and luckily Oracle was able to help me out. I'd try logging a support ticket in My Oracle Support.
Good luck, and learn to back up regularly!!!
