Blender linked object directory issue

Every time I link a library to my blend file save, and restart, the group disapers and Im left with an error saying it cant find the file. The error mentions the path but without the “C:” part. So it makes sense that it cant find it… The weird thing is it can find it the first time so why does it forget the correct path everytime I reload the file?
How could I remedy this problem?

Have you set the paths to relative in the user preferences?

I changed it to relative and then back again to the other and I think that may have had something to do with the problem but Im not sure. Anyway the problem is resolved.
I fixed my problem by changing the path manually in the outliner (set it to Library and corrected the path).
Not exactly sure why this happened but now its fine
