NavBot states current system is not in database and source system of trades is missing

What steps will reproduce the problem?
Hitting the Search link to get the calculated trades leads to this problem 
always.

What is the expected output? What do you see instead?

When hitting the search button the output shows 2 weird errors:
1. It states that the system where I'm currently at (i.e. Jita) cannot be found 
in the database (I have exported files from The Forge, especially when I was in 
the Jita system). Why does this message appear? Because Navbot doesn't know 
where I am the jump amount in the to section is wrong.
2. The From: field of the trade is empty. I have to find it out via the item 
price where I can get it from.

See the attached screenshot for the error message and the missing From: system 
information.

What version of the product are you using? On what operating system?
I tried NavBot-L and NavBot-N, both show the same behaviour. The only 
difference is that the NavBot-N version doesn't show the darker empty part of 
the profit bar, there is only the bright green part and the rest is black. But 
that doesn't matter, I just wanted to notice it.

Operating system is: Windows 7 x64 Ultimate (german language).

Please provide any additional information below.
Eve is running in german language. I don't know if this could lead to this 
problem, so I just wanted to provide this information.
When I run NavBot in the Webbrowser of the PC (and not the EVE Browser) NavBot 
still doesn't show the From: system, but the message that the system where I'm 
at is not in the database doesn't appear.
