Dt 4.091 & Vista Prob!!!

[PsychoStorm]

Hi Folks...

My problem is that I can't see my virtual drive in the explorer.
I can mount my Image but where should I open it?
In DT the drive is displayed but without a driveletter...

That all starts at the time I've updated DT 4.08 to DT 4.091...

I've followed the Steps in the Threads to fix this problem here, but it is still not working...

(same Problem by Alcohol120!!!)

I'm running VISTA Home Premium

PLEASE Help me, I'm going crazy, that sucks...

Edit

I've forgotten something to write:

When I install UltraISO and it asks me for install Virtual Drive I choose it, and THIS V-Drive I can see!!!

So, what is the problem...?
