When you create files on a computer normally on Windows all the files kind of get secured and binded to your compter/account. When you install Kronocard on a new computer and move all the data to the new computer it's possible that Kronocard doesn't work as expected. The most common problem you will face is that in the card view or any places in Kronocard that supposed to display a card image that image will be black. So no images all black boxes.
Don't panic! Just follow those steps.
After step 5 and 8 you will get extra message you just need to click on Ok.
Close that window and start Kronocard!! All must be fixed now. If not, please contact our support.
