I will do that. I looked through TIS again and looking at my notes it appears TIS said the system segment changed since the last time I recorded it, there is no history of the old segment though, so either I wrote it down wrong or it doesnt show a history in the TIS system when UF3 is added.

Old system segment was 12667418
New System is - 12667419

Thanks guys for your help.

If this is all it is I will put that system segment in and see what we got.
