I have just flashed my N900 and followed the wiki Method 1 in two steps:
1. Download the NITDroid Autoinstaller to ./MyDocs i.e. root directory of N900 and install it:
2. Run the NITDroid installer app from your programs list.

Right there is my first question. Step one says "...and install it"
Does that mean other than copying the file to /MyDocs you do something else before running the installer in step 2?

I just copied to MyDocs and ran the installer. It went through and said all good and should work, press any key to reboot. I clicked enter the installer closed but no reboot even after long wait. So I manually switched off. I turned N900 back on with keyboard out hoping to boot in Android, but there was no difference and no boot choice. I don't even know what I expect to see if booted correctly. And when there, how to grab and install LooxcieCam.
