Hi there,
I have this code:

You can't init an object more than once (well not an intended use).
You do:
SimParamnames = [NSMutableDictionary dictionary];
and later:
[SimParamnames initWithContentsOfFile: aFile];
which are both initializing the object. The second init is either
being ignored or perhaps corrupting

Bingo. LaunchServices does a 1-to-1 mapping between a file and a UTI.
That is, a file can have only 1 UTI. So if two UTI declarations claim
the same extension you are screwed.
