 ### If the app freezes in loading "Just a second" page:
 This is probably caused by an error reading the user configuration, probably due to an unhandled exception or new data added from MTGA that mtgatool is not handling properly. Bear in mind this issue is **not** because of a bad or improper installation, so reinstalling will make no difference. Altrough, you can roll back to a previous version safely if an update caused it.

 ### If you have any other unexpected behaviour
 
 First of all, uninstalling and installing again will probably not change anything, as most errors are either configuration errors or log provessing errors. Neither of them are solved by uninstalling. So, just to save you some time, make sure you have the latest version only.
