WordPress Slider Plugin Broken - Can you fix it?

**ONLY RESPOND IF YOU HAVE READ THIS FULLY AND UNDERSTAND THE PROBLEM** I have set up slider using the vSlider plugin for a client at [login to view URL] Up until a day or two ago, it rotated through 4 different images. Now it only shows the first image, with no option to view others. It no longer automatically rotates through images and the icons to choose image 1, 2, 3 or 4 are now gone. I wonder if this is a jQuery issue/conflict? We want to continue using the same plugin - if you can find what has caused it and fix it, that would be great. MAX BUDGET: $15 Can you help?
