If you used the autoscript and use Qt 4.1.3.0 you should be fine. Make sure your VPS is stable, usually that can is the issue when you experience an unstable node. You can always do a reinstall, that does not mean you loose rewards. I always suggest you do that after you receive a reward.
Have reinstalled now twice and been kicked off the rewards set.
Definitely something funky happening, because using VPS’s that fit the requirements and have been running for multiple months without hassle previously.
