I've been working on my project the last few days and everything worked fine. I am using Megunolink as a GUI to create input via buttons and value lists to control my device.
Till yesterday I got no problems, but when I tried to connect Megunolink today, it wasn't possible to establish a serial connection.
The "connect" button did nothing. And when pressing some Buttons, I get the message "Error sending: can't write to serial channel. Is it open?"
Uploading my programs with the Arduino IDE works as usual. (I tried different programs)
When opening a backup .mlpz-File from yesterday, the connection is established and everything works as intended. But when disconnect once, I am not able to reconnect.
After loading the backup file again it works till the next disconnect.

Hi, do you have a MegunoLink license? Those are the sort of symptoms you get when an invalid license key is used. Get in touch with use as firstname.lastname@example.org with your transaction information and we can try to figure out what the issue is.
