Eric, I am also facing the same problem. I found this problem after getting erros in the Forums. After creating the Forums when i go for forum-view it gives error dump. after a long search I suspect the notification module but not yet fixed. Really one problem with the .LRN is the installation order. I too got many problems in the installation. I crashed the db 3 times and started installing .. still not able to solve it. I am ready to provide as much information as possible to correct the installation as well as mounting of notifications.. although I am starting the .LRN now only..
