Nuska A lot of people are experiencing issues at the moment, myself included, only managed to find a forum work-around just before so I can access the forums, but posting still fails a bit.
If you're wanting the manual I uploaded the offline Construct 2 Manual download to my Dropbox for you. Additionally, if you need some help with using the program, hopefully forum access stays up for me and you can post a question in Beginner's Questions, where I will do my best to assist.
