Why can the instrument not be instantiated? That sounds like a deeper problem with the instrument that should be fixed.

@racostas I like the try catch, but I think other than the error log maybe a warning alert on the browser saying something like "Uploads to instrument BLA were not loaded due to an error" something along these lines so that it doesnt go unnoticed
