Thanks a lot for your reply! However, the conclusion is that I am actually a total retard haha. I have the idea that MultiBit never asked for my password before, but that might just be my brain fooling me. After a lot of trying out passwords I took a small break and focused on something else, and after that it suddenly dawned to me, that I actually DID set a password a long time ago. I'm in an honours programme in University and I haven't slept a lot lately (exam weeks), so that's probably the issue here.

I'm extremely sorry for bothering, and if anyone else sees this post later on having the same problem: Calm down, don't stress out, think clearly because you probably know it. My case is a special case because I am moronic and couldn't remember I actually set a password in the first place. But if you have troubles remembering your password, take a break and focus. If you know parts of the password, you could look into scripts, or use walletrecoveryservices dot com. They might be able to brute force your password (25% of the time).

Hope my stupidity has helped anyone out there, and also sorry for doubting Multibit, which is an excellent client!

Conclusion: I am a retard, but a wealthy retard!

Like Litecoin? It was released well over a year ago, I think.
