A few people have been sending in reports of Awasu crashing during startup. Thanks for these.
Unfortunately, the crash logs weren't giving me very much and I was under the impression that it was an intermittent problem. Thanks to Isaach for pointing out that this is not the case.
You need to get a new version of the plugin and unpack it on top of your existing files.
This is totally my fault - it just got forgotten as part of the upgrade processs. Oops and apologies
