Help required, unable to message co workers on Spark

As of 2 days ago I am unable to message any of my co workers and supervisors. I am able to log into spark successfully but when I click a name to message someone it does not pull up their name and cannot begin a chat with them.

If you have a helpdesk or any IT staff, you should contact them. If not, well, you can go into Help > About and tell what version of Spark you are using. Also on Windows, Mac, Linux?


I am using windows, spark 2.75 version 2.0

Thanks !

First, make sure you know your username, password, server (you can see this when you do Logout). Then you can exit Spark and go to C:\Users\User\AppData\Roaming\ and rename Spark to Spark_old. Then start Spark and enter your username, password, server. Login and check if it works now. If not, exit Spark and delete the new Spark folder and rename Spark_old back to Spark. If it works now, you can use it. If you need old conversation history, go to C:\Users\User\AppData\Roaming\Spark_old\user\youruser@server\ and copy folder transcripts to the new Spark folder.

that worked thank you!
