I am unable to build my place or play any game on buildism..

[Qwertygiy]

Since it's complaining about a missing file, try manually installing it from my working .buildism folder.

Download it, then copy the .buildism folder from inside it and paste it inside %temp%. It should say something like "Do you want to overwrite this file?" Check "Yes to all".

Then launch the editor and see if it works.
