So I installed jemplode 2.0 , whenever i try to upgrade it i get an error when it try to open the program.

For example i downloaded jemplode52.jar and then i renamed it to jemplode.jar and then i overwrote the file in my current jemplode directory and when i try to run the program i get an error that says

Unable to locate teh application's 'main' class. The class 'org.jempeg.empeg.emplode.Main' must be public and have a 'public stative void main(string[])' method. (LAX)
