Hi there, I'm kind of new to the whole bitcoin world. I used the classic multibit wallet without any problems.

But now I've installed MultibitHD on a Bitlocked USB stick. It was all working fine, until the programm suddenly closed, and I was not able to open it anymore (don't remember the error it was giving, sounded something like some installing files where missing). After that I choose to re-install MultibitHD, but I didn't write down my "wallet words" to restore my wallet. I still know my wallet address and offcourse my password. Is there any possibility to restore my coins?

Multibit HD is as the name suggests a HD wallet and works differently than Multibit Classic. The address is less important than the wallet files. Do you still have those?
See here -> https://multibit.org/en/help/v0.5/help_troubleshooting.html
for the typical locations.

I know it sounds kind of stupid to not write down my "wallet words", forgive me for that. And forgive me for my bad English, because it's not my mother language.

There are none for Multibit Classic.
