Yes u can if you still have a current subscription. The time line autel gave us was recommended to ease server load. U can update whenever u like. Just be aware others may be downloading so expect delays. Personally I would wait a little while and see where this is going before I update. You will loose the ability to run prev versions. Any backups u made will not work with new system update. My time is about up with autel and I will not download this new system update. If u have the time left on your sub I would wait and see. Good luck  

 No this is a function that came with update v1.29 and on I think. I do not know if turning wifi off will disable this funtion as it can not see new updates. I am still running v1.28 and have no such message. It is suppose to make life easier and tell you that there are new updates. If I want to update I will hit the update button thank you. You have to live with it as there is no going back on the system version. 

Do you mean the error message "maxisys has stopped", it has been solved already. You only need to connect your tablet with internet for a while. And also it is strongly suggested you upgrade your system program to the new version. Thanks.
