Can you please post your complete project or a shortened version that shows the error so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
Some UDB based Components may updated to a higher version in Creator 4.2 when you cleaning the components errors, new version components usually include more features and needs more UDB resource to support that. So if your project already cost almost all of the UDB resources in Creator 3.3, then update project in Creator 4.2 may get error message like USB resource is not enough to use.
