invalid session fault

unable to maintain a valid session with .NET. it keeps timing out every few operations. i've set the Timeout to various intervals (it's currently set to 10 hrs). i've changed CookieContainer(2) to CookieContainer. made sure the account number was in the header of the cookie. i'm very frustrated that netsuite makes these changes without taking the initiative to inform its users.

think about it--their customers are their biggest source of income. their customers expect a stable environment/platform to work with. changing things around every now and then that breaks code for large applications without giving warnings in advance is just bad business. equally bad is the fact that the developer guides and sample code are inaccurate, and that it seems you can't even completely download the ERM and CRP sample apps. for me, at least, they stop at 35% or so.
