Selected Library is Invalid

[ManitobaMoose]

Hi,

I haven't been working on SAS for a while. I got back from break and suddenly I can no longer refer to the library that I have been using for months. The library name is LEARN and it I am using SAS University edition with VirtualBox.

When I click on the library properties for LEARN I get the message that the library is invalid. When I try to reference the library in the SAS programs, I get the Error message that the library Learn does not exist. Help!  I have tried to delete and recreate the library, and it works for a minute or so (whereby the SAS program recognizes the library), and then I get the same problem.

Below is the log form one of the programs. Thanks for your help...

I RECOPIED AND PASTED THE LIBNAME INFORMATION AND SOMEHOW IT NOW WORKS??? AT LEAST FOR NOW. i have no idea why. Anyway, no solution needed for now. If it stops working again, I will repost. Thanks.

Maybe you had a hidden character somewhere in there that wouldn't display. Such Heisenbugs are the worst of the species.

Most probably you somehow managed to remove the directory learn from your shared folder.
