Hi Johnny,
We understand, it took long to reply to your query however the work was under process at the back end.
Our engineering team reviewed this. They are working on a fix, which will be released in a new SDK on Developer Connection. Please be aware that Win 8.1 is still in beta, thus changes can be made that affect our SDK. We will try to resolve them as fast as possible.
We will keep you updated on any further development on the same.
