Endnote not recognizing previous endnote citations

The day is started using EndNote, my writing became like a curse to me. It created difficulties in every step: from installing to writing my manuscript. They have the worst kind of customer service. I don’t understand how this kind of company exist in scientific community. This thing is not a citation manger. It’s more like a citation ***edit***er. Now, it’s 11.07 PM and I am just pissed of with this ***edit***ing software for last 24 hours this time. This is a pain! This is really a pain. The latest thing it did: it don’t recognise already inserted citation. It just creates a number which is already existed and then mess it up while updating citation! ***edit***er! I know, you will be continue to make money out of this ***edit*** software and researchers will continue suffering!
