Thanks again, but I'm not using the account pages like you normally do.

The program I'm working on collects the data from the account pages automatically and process them offline, but for that I'd like to be sure how the product update system works, so the data are being processed correctly without errors. Therefore the specific questions in my first post. They should be easy to answer - I think any vendor could answer them but I don't like to bother any of them if I can get the answers here.

Otherwise, if there is a FAQ for vendors with info on how files are being updated you could point me to, that might do as well.

Thanks!
