Thingworx viewer: Troubleshooting viewing experiences

Hello all,

          I am having trouble viewing my experiences in thingworx viewer, I followed the following steps:

          Step 1: I set a thingmark to my model by dragging and dropping it.

          Step 2: I went to my experience and set a thingmark number (e.g. 10001:1).

          Step 3: I saved and published my experience.

          Did I forget a step?

          Is this an error in Studio or Viewer?

          Also, I verified my ThingWorx Experience Service as well as changed my experience service URL to reflect the experience service.

            I was successful in using studio and viewer last week however, following the same steps thingworx viewer does not connect with my models or experiences.
