WebPlus X6: Major problem with page links

Hi Everyone,

I am using webplus X6 to build my website, www.worldprivilegecard.com and the site is fairly large, I have around 100 pages.

When I make changes that influence the whole site and do a Publish All pages, or publish a larger number of pages it screws up all the links to internal pages.

For instance:

from this page:

http://www.worldprivilegecard.com/partnersbyname.html
you can click on "AMALGAM FINE MODEL CARS" which shoukd bring you to the corresponding page. But after a number of updates it actually brings you now to the page of "LANCELOT LANCASTER WHITE".

Also, regularly and random, the links to pictures placed on pages are changed to other pictures . For instance last week I did a PUBLISH ALL TO WEB and the footer was replaced by a random picture from my hard disk.

PLEASE HELP!!
