InfoPath Dev

I am quite new to infopath, so I still hope there is an easy way to solve my problem...  I was creating a form for collecting information to a project. This form contains also a control to attach documents related to the project. The form was working well until some of the users start to attach large files. I changed the share point server ...

I run in the same trouble. Even if I changed the configuration for InfoPath Forms service on the Share Point Service to 50MB. Also the machines.config is configured to let SharePoint operate with large uploads. Anyway, if it comes to files larger then 10MB I got this error. Would be cool if someone knows a solution to post here :) cheers
