marlin arduino compile error

Hello everyone,

It's been a while since I played around with my reprap. But something weird seems te happen when I'm trying to compile Marlin. I posted the errors here under, but I don't know what's wrong. I don't seem to find a Wstring.h file in the marlin zip-file...although I have used that zip-file in the past without problems...

should I just find a new Marlin version? I'm on a GEN6 board and standard mendel.

Thanks for your time!

Wrong version of the Arduino IDE. There were major changes between 0023 and 1.0.

Thanks for your thought, traumflug. I could try to reïnstall Arduino, although it seems odd that this would be the cause of my problems.

I have Arduino 0018...and I didn't reïnstall it lately...it seems weird to me that the arduino IDE can be the cause if I haven't made any changes to it since the last time everything worked fine?
