I just performed a "restored system files and settings from a restart point" on my PC, and now I no longer have access to my Student Edition of ArcGIS that was installed just a few days ago. I probably chose a date one or two days prior to the date of me authorizing my student use with an EVA number. The ESRI website will not let me reuse my previous number because it has already been "used" once. How I can I reactivate my Student Edition, or do I need a new EVA number? thanks Ed
