Student License won't activate

Due to some problems I've been having with my computer, I've rebooted it completely and erased everything. I then installed the SOLIDWORKS setup package from the community page as I am a student and am eligible for a student Edu package via a serial number provided by my school. Upon installation of the SOLIWORKS app, a dialogue box prompts me to activate the license (at first I had 30 days but then minutes later it says I had 0 - zero - days of grace). Whenever I try to activate it says the the activation has exceeded the limits and even though I try to deactivate on my computer it says that there are no products to deactivate.
