Editor Showing Errors With Aptana Studio 3 After Update

I have used Aptana Studio 3 for the programming of python for quite a while and never had problems. But after the update today (the version now is 3.5.0.201401092130-09012014213131

Solution 1:

Not really a solution, but this workaround worked for me. After reverting to a previous version (3.4.1 in my case), the behavior I described above still persisted. But after I switched between the PyDev and the Web perspective a couple times, the editor went back to the normal behavior (the perspective switching didn't do the trick for version 3.5).

When I talk about version reverting, I don't mean the build in option (I tried it, but it just showed an error). I deleted the Aptana Studio 3 installation folder and downloaded the 3.4.1 version from this website.
