The question: which version of PGE Editor you are using?
- If you are using Beta3's PGE Editor, it's very old. You must update it
. New config packs are NOT compatible with older versions of PGE apps.
- If you are using Laboratory build (SMBX2 side PGE updater does installing of Laboratory builds!), you need to get latest config packs here: http://wohlsoft.ru/docs/_laboratory/config_packs/
as config packs in the front are targeted or stable builds.
Note: the "SMBX 2.0 Integration" pack that stored is here, it's update for Beta3's config pack which patches old to make it be compatible with newer PGE Editor.
