I am a masters student with an advanced single use license. Last week I used the spatial analyst toolbox for a report. This week I got an error message telling me that I didn't have a license to use the spatial analyst tools. The customer support walked me through a few things but could not come up with an answer as to why the Spatial Analyst tools would not work but suggested I post a question here and see if I could get some help. I'd love to get this issue resolved quickly. any ideas?
