If you've experienced problems getting into Habbo Hotel after updating to Shockwave 11, then that could be because of problems in Shockwave. We have good news for you though: a new version is available for you to download from the Adobe site and this will solve the problem.
If you can get into Habbo Hotel then you don't need to do anything. Go in now and have fun!
Your Shockwave version should update itself automatically in the next month, but if you have problems with the current version, here's how to update it:
1. Get the latest Shockwave Plugin from Adobe's site, and install it according to the instructions on the Adobe site.

2. You should now be able to get into Habbo Hotel
If you still cannot get in, report it to us in our tech forum.
