If 0.3 worked, It's very likely that RC3 also works. I had added a couple of security protections that seemed to avoid instalating in some conditions. And that's maybe what is happening to you.
And thanks for your encouragement
Er, well, this is preRC3. As you know some things tha I have added may be incomplete or not work at all.
This is not recommended for people currently using RC2, although you should be able to upgrade KSMAS using this setup script. This is just a preview to test that the fixes in the setup script work.
You will notice the new memory limiter, use it at your own risk and, what's more important, do not relay on it. It's not finished yet. It won't ruin your server, but it could ruin your configuration file and your rotating avatar, so don't touch it, for the moment.
Just another little thing. This version is supposed to be only for testing. Its is not recommended to keep it and you should upgrade to RC3 as soon as it appears.
All further blablabla is rather irrelevant: Use it at your own risk
