Hi Guys and Girls I have had this problem and never managed to get webstyle to work until now.. there are two ways to get it to work it you have installed webstyle 4 and it has copied your templetes across then to get the save button to work all you have to do is: you only do this with one directory at a time copy all the files from a directory in the templetes dir and then paste them into the directory on your C:\Program Files\Xara\Webstyle 4\WSTemplates but DO NOT OVER WRIGHT AND FILE THAT ARE ALREADY THERE just add the ones that are not do this for every dir and your problem should be solved.
Second option if that did not work uninstall webstyle4 and download the demo version from internet install it and then click on a templete it will ask you for your xara logon details but once this has been done it will then download all the files and updates and all will work fine plus as a bonus you dont get the please insert cd box any more.
hope this helps it worked for me. mail me if you need help.
