I have downloaded and successfully unarchived the "FiaW_Day4_ProjectArchive.zip" file. However, when I try to open the workspace via the "Switch Workspace" option under the "File" menu, none of the packages appear in the "Package Explorer" window.
I have successfully downloaded and opened the workspaces for days 1-3.
We are currently fixing the project archive zip and will replace it on the site within the next few days.
Another thing, you can always pull each starter and solution file from each exercise. The links are at the beginning of each tutorial.
