Uninstalled idrive, went to DSM6, and tried re-installing 2.03.18 thinking that 2.03.18 is bugged with DSM 5.2 and only works with DSM 6. Same problem. Spinning circle.
Hope this gets fixed.
But, honestly, debating on just using Cloud Sync now instead of iDrive since you can do multiple sources and multiple targets and be able to use encryption going to the target.
