Mindjet team, your cloud sync is awful and unreliable, please fix it or remove the service completely. The "check in/out" is also not required for individual accounts. Perhaps get rid of your cloud which does not offer any kind of revision control and use Drobox, iCloud, or Google Drive. I've lost more data with Mindjet in a month than I have with any other cloud service over many years. Again, without a proper revision control why do you even bother hosting files in the cloud? Please fix your system, and I wouldn't mind a refund, as your subscription model sold me on cloud, which is clearly smoke and mirrors.
