I deleted the cache file and it did not help. When SiteAssite ask to update the other pages it crashes Dreamweaver.
I deleted the configuration folder, mistake. Now I lost all my pre-sets and plug ins. I tried to add SiteAssist, but it know nothing about the website and wants to start a New SiteAssist session and not work with what I have already done. I have a backup of the configuration folder I just need get it and restore it.
