DB failed to open

[marcodut]

I just started the first time to install Armory (Version 0.94.1).
After more than five days of "Initializing Bitcoin Engine" I got the following error message:
DB failed to open, reporting the following error: Failed to open db C:\Users\name\AppData\Roaming\Armory\databases/headers
(Das System kann den angegebenen Pfad nicht finden.)

How can I fix this?
(It is on a Windows7 PC)

Thx marcodut
