Welcome to Visual WebGui
It is very hard to say without having more information on your application, what may be wrong. To save all of us time, please clean your application project, zip it and email it to the support email address and we will take a look at it. You will find the email address for support in my signature. Please rememeber to include in that email the full Http reference to this thread and also please post here when you have sent the email.
Please remember to include some basic report so we can test and run your project preferably out-of-the-box.
You may have to rename the .zip file to another extension (like .xip) so it will pass through email filters.
Hope this helps,
