Need help STAT.

I just follwed all th einstructions to a 'T' and I am getting this:

"1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'apsona_index');'' at line 1
in:
[SELECT id FROM admin_files WHERE page = '#" title="Apsona ShopAdmin - opens in new window" onclick="apsona_showPopup('apsona_index');']
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields."

I can now no longer access anything...all I see is the menu ribbon at the top and when I try to access anythign it gives this error.
