Did you tried the one I told you (gave you the link ? enigma2-plugin-systemplugins-crossepg_0.6.2-svn-300-r0_mips32el-nf.ipk).
We had it pre-installed in our older images, did you tried to install the older version and then upgrade online to have the later image updated ? It should work and keep the CrossEPG inside that was working fine.
CrossEPG seems to have been abandonned on OpenPLi, as now they use EPGImport that is preinstalled on our images.
