How to backup .wyp file?

I have a wyBuild project: Solver.wyp.How can I move it to another folder (like dropbox) and have it still work? It "works" fine until I click 'build wyUpdate & updates', then I get this error http://gyazo.com/82cdbaad7833f95a94a62f08678b6b40

Basically program tries to navigate from previous location, to my project files, but navigation from new location fails ("..\..\..\" etc doesnt lead to my files).

How can I update it so wyBuild knows that Solver.wyp is in a new folder?

wyBuild uses relative file paths. This means you have to move the files along with the project file.
