Answer 1

I had the same error and I fixed it by changing the workspace folder in Aptana: "General -> Startup and Shutdown -> Workspaces". I removed existing and added following one: "C:\Aptana_Studio\workplace" (instead of a workspace folder in my user profile).

JFYI: I found this error occurred after I've installed Eclipse for Java.
