Its had some difficulties because I can not upgrade anymore. But today I went to my Diabetic Carelink site and can not get on it because I have to have OS 10. 8 or higher... very recent change on their part.. I am not eager to have to buy a new computer but want to use that site. To down load the infor off my insulin pump and continuios gluc monitor. Any thoughts or ideas bdesides buying a new computer. Hate being forced into buying a new computer.
