You could rebuild the view yourself: Right click on Audio and select "Add Library View". Chose "albums".
That should work, though it did something rather weird on my Mac. I think it's probably just a Mac version issue; not sure.
If that doesn't work, you can customize the view to make it just like the original. Or, you can restore an MC Library Backup. MC makes them automatically every few days. File > Library > Restore Library . Keep in mind that you will probably lose any changes made between when the backup ran and when you restore it.
