Firstly, check that you are using wMM full edition.I just installed webman 1.45.10. I no longer have webman launchpad. I no longer have the program to install the pkg. The folder "read my games with Webman" disappeared?
The edition is displayed at the bottom of the localhost/cpursx.ps3 page. Or you could check the size of the webftp_server.sprx file. The full edition should be about 165kb. Other editions would all be under 160kb...
Secondly, make sure there is an existing wm_launchpad.xml file otherwise webMAN-MOD will not create the launchpad game list.
Create an empty wm_launchpad.xml file in the /dev_hdd0/tmp folder if there isn't one then reboot the ps3.
Due to Refresh XML increased memory usage while creating 2 different xml games lists, one for webMAN-MOD games & the other for the launchpad entries, I also suggest that you check the plugin memory usage setting in the setup page. Don't use Min memory settings even if you don't have that many games. Min+ or Standard should probably be your minimum settings from now on...
