You can upgrade your 4.4 trial project to 5.0 SBE, by following one of those methods:
1. Download the 5.0 Project Manager from your account downloads directory and run it. Then you can import your 4.4 project and upgrade it.
2. You can download the 5.0 Project Manager and create a new 5.0 project. Then you can copy the contents of the bin folder of the 5.0 project to your 4.4 project and replace all the files inside the bind folder. You will have to restart the project afterwards, so that the upgrade scripts are initiated. After the upgrade has finished you will be prompted for your 5.0 license.
