Kuk and Kaiser campaign available at http://www.freeweb.hu/kukgen/download.htm and http://www.dirk-cremer.de/hg/eng/pg.htm. If your system is case-sensitive too, you have to extract all files, then rename them all to UPPERCASE, and only after that copy them to PGI folder.
Kaiser: But when I trying to compare original scenarios with converted ones in lgeneral, I have some... I don't know... issues... it's seems for me that either some units are missing or may be it's me who fail to convert correct scenario... Unit icons convert more or less correctly, but there are a lot of black dots on icons after connverting. So, lgeneral displays only some parts of some units. And it's hard to see them...
2. K.u.K. campaign.
I cannot convert any scenario from it by using lgc-pg neither in "campaign mode", nor in "custom scenario" mode. It says:
segmentation fault and crashes.
About campaign tree. In attach there are two campaign trees for K.u.K. campaign. On from original archive, the second one from forum where kuk campaign had discussed.
I think the riginal one (Camptree.jpg) is more accurate...
