Cannot make it work

[mabra77]

Hallo !

I used MediaBox for some time, but I have had to install a new box,
which is a virtualbox machine, like the used one before.

There ist something strange and I cannot make it usable.
Installation and zip-use are the same. I have the latest version.
I am using windows7 enterprise, en, like before.
I am using the build-in admin account, but get the info-box, that
I have to be admin. For this box, UAC is off and I choose
the account to work with - this is like on the orig box, where it worked.

MediaBox starts and minizes.
I tried browsers: FireFox(36), IE(11), chrome(41).

a) MediaBox starts, no media is recognized.
b) MediaBox starts and browsers cannot connect with https.

I found a thread to make a reset (netsh). I re-installed.
I cannot make it work in any way.

I just need to understand, where to look.

Thanks any way and
best regards,

Manfred
