SOLVED: SharePoint Designer Workflow updates doesn't work!!

This time we faced an issue where even after updating workflow steps conditions and actions it doesn't seem to be applied on the server...

The solution was simple as it seems that SharePoint Designer saves local copies from your servers, and although everything seems OK, this prevents it from updating the workflow ..

To solve this issue:

1. Close SharePoint Designer
2. Go to

   %LOCALAPPDATA%\Microsoft\WebsiteCache

   Or, on older versions of windows:

   C:\Documents and Settings\%USER%\Local Settings\Application Data\Microsoft\WebSiteCache

3. Delete either (choose one, based on how annoyed you are by now):
   1. All folders.
   2. The folder that "looks most like your site" (can be more than one: site, site(1), etc, and should be the bottom level site, not the root site)
   3. The relevant DLL in that folder.
4. Start SharePoint Designer, save the workflow again, it should be ok.
