Aion RainMeter

Hello,
I have a problem with my rainmeter. Sometimes it works normal, but it often just stops working without any error message.
This may happen when I farm in open, but it also happens when I'm for example in an instance like PW, so I don't really know what's the cause.
When this happens, I need to restart my computer/relog into my account but I can't do this when I'm in the middle of a boss fight >_> Then it works again.

Is there any solution how I can prevent this case? Or is there something I could change so that it does not always stop working?:/

It stops working suddenly while the game is still running? or after you start the game again?

Y it stopps working suddenly while the game is still running ;/
This is why I can't tell what's the cause of it, since it does not matter if I do open or instances
