Paintstorm completely messed up and can't use it :/ please help

[harle]

Hey

I have a HUGE issue. Yesterday Paintstorm was working just fine for me, however when i opened it today it was completely messed up. It loads as always with the grey screen and paintstorm studio logo but as soon as it would swich to the drawing platform with the ui and the canvas it starts to flicker and go crazy. I can only see the white deafult canvas with no UI at all. If i click anywhere it stops flickering but there is still no UI only the canvas. I can't paint anything, sometimes it swiches the cursor to color picker but this is it. I can zoom in zoom out, but othervise it is unusable. Has anyone experienced this program?
I have an Xp-pen display tablet but i haven't move the program window to the display and it behaves the same if i unplug the tablet.

Thank you for any help!
(I tried to uninstall and reinstall paintstorm but it acts the same way nonetheless :/ )

Try to manually delete "Documents/Paintstorm Studio/" folder and reinstall Paintstorm (better the new 2.40 version)
