Romcenter crashes when trying to add folder

[Former user]

I was adding a folder to romcenter. The folder select window pops up. so i went into a folder on my computer think i added the folder or i closed the folder window, i forgot that part went out of romcenter and i changed the folder name of the folder i had selected in romcenter and went back to romcenter. and tried to add another folder. but the folder window opened AND romcenter got stuck i tried to close romcenter and open it again. but still i got stuck when adding a folder. i think its because he was looking for the folder which i selected earlier, but changed the name of the folder so romcenter wasnt able to find the folder anymore. and gets stuck
