I checked the memory usage and it points to 98% work memory usage. When I tried downloading a previous version that I was sure worked, it displayed the same error. I'm adding the Memory screen as an attachment. Attachment Captura de tela 2025-01-17 110253.png (282 Downloads)

Best regards, Wizard

Check if you can reduce the size of the DBs. Please also post the TIA version, CPU MLFB, and CPU FW version. If it is safe to do so, you might try resetting the CPU to factory defaults and then downloading. That is not a final solution but might get you working in the meantime.
