Hey, that error is most likely because the Graal path was set incorrectly, and now Gonstruct tries to index the entire hard drive and encounters a folder that it can't access. Ideally it would just reset the Graal path at that point but..

What you can do, is to exit gonstruct, delete the folder C: \Users\<your user name>\AppData\Roaming\gonstruct (or type %APPDATA%\gonstruct into the explorer file bar) and, when launching gonstruct again, select the correct Graal folder in the dialog that appears. Hopefully that resolves it.
