Error Message Program Won't Open - Have No Mail Access

What on earth do I do now?  It tells me to contact support but it seems the only way I can get support is through this forum.

Thanks for any help

Hi Ellen,

It seems that another program is accessing your database so eM Client can’t open it. Usually, this is caused by antivirus program so please try shutting it off and restart eM Client to see if it helps.
