Are you using libraries from wayland and nkrkv that need updated to work with new version?

Do you have any `xod` folders under your ` __lib__ ` folder with other libraries (usually in `C:\Users\YOUR_USERNAME\xod\ __lib__ `)? This would indicate you made changes to the built-in nodes and are not getting the latest copies when you update XOD. If any xod folders do exist in library folder, you can delete (or just rename) them so XOD can see the latest updates for those nodes.

I hadn’t realised that the [draw-xod-logo](https://xod.io/libs/wayland/ssd1306-oled-i2c/draw-xod-logo/) node in my [ssd1306-oled-i2c](https://xod.io/libs/wayland/ssd1306-oled-i2c/) library needed updating to work in the latest version of XOD. Thanks @c-petersen and @gweimer for letting me know. I’ve just published a fixed version of my library (v0.0.7).

Thanks @gweimer and @wayland  
now it works fine 🙂 only the “nkrkv” lib is not working anymore.
