Cannot change Widgets with Clear Theme by Invent Group anymore

Hi there,

I am using wordpress version 3.5 with the Clear Theme (version 1.3), provided by Invent Group.

So far, I did not have any issues. Suddenly, after deactivating and activating the theme again, the widget area doesnt work anymore. When I try to drag and drop widgets, the backend just does not respond anymore. I ahve tried installing the theme again for three times now…with the same result.

The drop down menu on the left side in the admin area of wordpress does not work neither with this theme.

How come? Has anybody of you had similar experiences? Could you please help of provide some feedback on this issue?

Thank you very much!
