Hi,

please ensure that you are now running the latest version 3.5.8.7,  
since there was a mandatory hardfork (A).

The hardfork was successful and we are in the process of confirming all exchanges and services are on the latest version  
to ensure a smooth experience going forward.

We will contact you again in 24-48hrs when the process is complete.

Hello again,

several users have been experiencing further sync/forking issues in Gridcoin version 3.5.8.8 since yesterday ☹

Please shut down the Gridcoin wallet and hereby extend the maintenance period for a few days until things have become stable again.  
We will inform you again!

Sorry for the inconvenience,  
Erkan YILMAZ
