Hi,
Seems like you opened three threads here, about Open ERP. I think there is some confusion. These threads are related to Google App Engine, issues found on it, and releases on that platform. It should not be used as a place to ask anything about any software.
I would suggest you to go on Stack Overflow and ask your questions there, but even there, your questions seem too broad and will probably be off topic as well.
Start working with open ERP, and when you have a specific, reproducible, and narrower question, post it on Stack and try to get help over there. This group is definitely not the right place to ask these things.
Thank you,
