Errors thingworx mashup design
Hello,
I have some errors when I open any mashup design in my Thingworx, I can't see this window and application.log show this:
**** Unable to fetch license file with device id e806cab0-2631-4cfa-9d0f-c7245b2ac6aa
**** Could not send response message. APIRequestMessage [requestId: 1545434, endpointId: -1, sessionId: -1, method: POST, entityName: SPARX_449223_THINGWORX_RemoteThing_8bf91c0e-2df8-4d23-a51a-7361539dafff, characteristic: Services, target: NotifyPropertyUpdate]
Someone knows about this error and could help me?
Thank you in advance
