Cannot update applications

When I try to update applications from the Suite Manager "Manage Apps" function, it fails with the error message "Unable to contact the server. Verify your internet connection. Try again later and contact us if the problem persist." The internet connection is OK, Firefox portable from the PenSuite is working fine, also right clicking an application in the "Manage Apps" window and selecting "Web Page" opens the application's page on www.lupopensuite.com

Dear user, I'm working to improve the Suite Manager and resolve these issues. At the following link you can download a pre-release of the future version of it:
http://www.lupopensuite.com/downloads/man/Manager.exe

Place this executable in "[suite]\Launcher\Manager" folder. Than you can use the Suite Manager normally and report me if it works fine or present other issues. Actually I have:
- added the support to auto-update also the Suite Manager itself (so in future, if I'll release new versions of it, you could update them automatically)
- resolved some issues with update system and proxy conflicts
- improved some features of the manager (like the Check Updates and the Manage Apps features)

Many thanks for the fast reply.
I downloaded Manager 3.0.15 from the link above and replaced the existing 3.0.0 - voila works like a charm. Great tool that suite, simplifies my handling of portable apps a lot.
