An Error Occurred (Gmail Sub Calendar Won't Sync) Screenshot Attached

Since I started using EM Client, its downloaded all the sub calendars in my gmail account, all but one. I checked to see if there was any difference in the calendar settings, compared to the others, and I don’t see anything. Please help me figure this out. Its very frustrating when I open my program every time and get this warning. ![](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1622235/RackMultipart20170715-84125-kt49nc-2017-07-15 2 inline.png?1500124253 “Image: https://d2r1vs3d9006ap.cloudfront.net/s3_images/1622235/RackMultipart20170715-84125-kt49nc-2017-07-15__2__inline.png?1500124253”)

Can someone please help me with this??
