Running NW6 SP2, eDir 8.7
iFolder 2.0 in protected memory on 1 cluster node only

I was having problems with the server, and and the TIDS lead to
re-fixing nici.
I noticed that there was a new nini (2.60) so of course I installed

Fixed my server problem, and it even loads httpstk, portal ,nile
without out the timeing issues better.

However, iFolder will not load. Apache, theads, clib - they all get
an init failure and a memory protection error is
generated for protected memory

Any thoughts of where to look next on this one?
I've though about re-installing iFolder (2.1 upgrade) which we have
