Had a frustrating day today!

I thought I would add a slideshow to my blog! Well, not as easy as I thought. I managed to add some pictures to my slideshow and it looked great, then i decided I would add more pictures and oops! I did something wrong, cos I ended up with 2 slideshows on my page and now I don't know how to delete them and start again! I have spent the whole afternoon on this and I have ended up emailing Slide Customer Support, I hope they can help me out!
