WARNING: DO NOT USE THE 'UNINSTALL' OPTION OF v0.6 and v0.6.1.
Unfortunately, I have just received a message from longam telling me something went terribly wrong while he uninstalled S3D, losing files/data unrelated to S3D. I don't know why this has happened to him at this point and will have to investigate it to be able to confirm it.
I have not experienced this before (nor have others likely, otherwise I would have heard it before), but for the time being I advice everyone not to use the uninstall option to remove S3D. Simply delete the folders by hand if you want to remove it.
I will have to investigate this issue. Until then, while it may work fine for most of us, don't uninstall (or even install v0.6.1 over v0.6 as this will run the uninstaller of v0.6 automatically!!!). In all my life as a developer I never experienced anything like this, and this kind of news is the worst that a developer can hear. I am so embarassed...
For the time being, I will also pull the download of my site.
Again longam, if S3D is the cause I deeply apologize. I hope you can recover your data.
