Error 525 typically means the Smaart demo was previously installed on the device, then removed, and the license timer has run out. In abnormal circumstances, this error is caused by changes to/issues with the system time and date.
Unfortunately we are not able to repair the demo version of Smaart, and you will need to download the demo on a new device. Otherwise, please contact email@example.com for further assistance
