Website X5 Evolution version 8, fully licensed

The application was working fine. I did updates on 18th March and looking back, it appears on that date a New Site backup was created (not by me) 

The application wouldn't open up the .iwp main page to load the website as it can't find the location.

When I load Incomedia X5, I get a black box in front of the main screen. Wehn I try to either create new or launch existing site, I get  message saying run time error 35600, index out of bounds.

website :www.zumbainbristol.co.uk

Can anyone help please - this site is critical right now as customers are directed to look there for information about current changes to my business and I can't make any changes.

Thanks

Philomena
