Sales Reports Problem

Hello to everyone!

I am using 2.2.1 community edition, and I have just created a sales report, but I have selected to provide me data for all the years and this is probably crashing my sales reports section. When I am selecting sales reports it takes for ever to open and at the end its just a blank page! Does anyone know the direct link to manage reports so I can delete the report? or any other solution as to where can I find the report via ftp and delete it? Or anything else is welcome! Thanks in advance!

Your lucky on 306 the sale reports don't even open for me. Never mind I can change the colour of the menu background easy so my business is safe.
