Sign in Error

Here are the steps he told me to do.

I have done all the tips from the first mail except for using another browser because my company doesn´t allow other browsers than internet explorer. As I tried the last tip their was the same error like before.

The things from the second mail didn´t work as well on my computer because I am not the administrator.

Thanks for your help!
