Sorry you are having problems, is this with the demo or the full version?

I am assuming this has started happening since the latest update? I'm currently working on a fix as there has been a few complaints about the latest update. The new update to fix these issues will be out in a day or two. Till then, since you have the Steam version, if you go to your Steam library, right click iVIBRATE Ultimate Edition > Properties > Betas > v3.03 (or any other version on the list). This will roll you back to any of the previous versions available which should fix this issue until the new patch is out. Sorry for the inconvenience.
