Update the UI ASAP. 1st top priority. The starter of the topic is 100% right. Just remove all the outdated now, fantastic super wow complex backgrounds with shadows and flashy corners that are influenced by Windows Vista and Windows 7. Even drop down menus animations would not need if they are acting like the computer is 486. You do not need to reinvent the wheel, just look the top 10 competitors, change the colors according to your company, put your logo and you are there already. Simplicity is everything. And mouse hover change color of a link was always important in the UX that is still not implemented.
