If LAppSter has crashed while executing, it is imperative that you send the error report after crash (look to notifications).
It contains the app stack and helps me to fix the error fast and easy within hours
If you have found some other problem (no app crash), try first to search for the equal inquiries in the comments below... maybe is the same problem already solved!
If not, so leave a new comment with a description, which helps to reproduce the same problem.
If you have a possibility to take screenshots, please do it and upload the images to the comment
