Block Load: starejše različice za prenos

Block Load v4.2 contains the following changes:
- Implemented a new project management system. Each project is stored in a single file that can be placed anywhere and moved or renamed at any time. The program remembers the location of project files and displays them on a ‘most recently used projects’ list.
- Implemented a new software security scheme using a license key. The license key is issued when you first license the software and expires when the license expires. A new key is provided each time you renew the license to extend operation for another year. Note that the license key is associated with your license, not a particular version of the software.
- Implemented a new installation scheme. Version 4.2 installs as a standalone software program. Installation of Carrier X Builder Framework is no longer required.
- Implemented several minor enhancements and corrected program operating problems. Please see the What’s New in Block Load topic in the help system for full details.
