Does seriously no one have any experience with Quick Fix 4.0 Batches and any expertise in my question about the batch age?

I am sorry if I constructed my question originally in a convoluted manner, but basically, What is the general consensus on minimum shelf life for QF 4.0 Batches?

I've read 18-24 months is the shelf life. I've also read 1 year.
As stated earlier mine is 11-07, so that would make it 13 months old.
Does ANYONE think there's a chance my batch might have been too old?
Thanks a lot for any intelligent input.

Yours truly -
Walddo
