We’re facing with issue to set the license key:

We’re using Aspose in WCF Service, which is called from Web UI. Service runs fine, but in one time it stops to generate PDF files with the error, mentioned above. After the service restarting, it runs fine with all file generations. This problem is getting very annoying. Can anyone advice where we can have a look or what to do here?
We’re using Aspose.Pdf.dll for .NET - 220.127.116.11
The workflow, which we’re using to init aspose:
We have the AsposeManager class, which is created per request.
public class AsposeManager
private static Aspose.Pdf.License _asposePdfLicence;
private static Aspose.Words.License _asposeWordsLicence;
private const string ASPOSE_PDF_LIC = “Aspose.Pdf.lic”;
private const string ASPOSE_WORDS_LIC = “Aspose.Words.lic”;
protected Aspose.Words.Document ContainerDocument;
_asposeWordsLicence = new Aspose.Words.License();
_asposePdfLicence = new Aspose.Pdf.License();
_asposeCellsLicence = new Aspose.Cells.License();
May be it was not good idea to init Aspose per request and create a singleton?
Thanks in advance
