Another Google search (which you could easily do yourself) suggest that the crossplattformui-package is... from your MTS MBlaze 3G/4G stick. It looks like that this package borked something pretty bad.
You could
- try to remove the package (which can be hard to accomplish for a beginner)
- try to follow the link above, at least the thread title says the problem was solved. Didn't read everything myself.
- reinstall the machine and never ever install proprietary software for your stick again but look for open source alternatives
