How to fix the following problem when launching an Amazon EC2 Intstance under Eclipse:
“Unable to launch instances: invalid BASE64 encoding of user data”
I had no idea what this meant and I couldn’t find anything in Google. So When I saw the dialog had some “user data” I put in there (just a few comments), I took them out. Just delete anything in the “user data” textbox and launch again. I never have this problem with the console. Maybe this is just an Eclipse plug-in bug?
