Welcome to the forum. I would recommend re-attaching the drawing references. There are two ways.
1. With SW open, go to File > Open. Browse to the drawing. Highlight it but don't open it. Click on the References tab at the bottom of the dialog box. Double-click on a file name to change, or in your case to re-direct to the correct file.
2. In SolidWorks Explorer, find the drawing, click on it, click the References tab, then RMB on the file names and choose "Replace".
Did you try what I suggested? And if so, did it fix your problem?
