We have been using the Total license for a while now, and recently we started getting the trial version message on everything. SetLicense is definitely being called, the expiry date in the license file is 20180526 and we are using version 18.5. Is our license no longer valid? This has been working fine until recently (not sure exactly when it started happening). We have not updated the Aspose dlls or changed the code that deals with Aspose.
Update: Please disregard this. They only had the Aspose.Pdf.License being set, nothing was set for Apsose.Cells.License.
