I kept reading about how to rebuild the cache but the comments were'nt very clear, then I figured it out so maybe this will help someone else.
1. Open Alfred
2. type gd and just 2-3 letters (generally any letters will work)
3. Once you see some results, just press ⌘⌥⌃ on your keyboard and you should see the text under the first/highlighted result change to "Force Cache Update"
4. With those keys held, just hit ↩ (return) on your keyboard to start the process
Note: If you type more than 3 letters and Alfred says, "Search "blah" on Google Drive's website", you've entered too much and it won't work.
