Hi! I was trying to install playblock, just to get it out of the way for whenever the next movie night is. It got to ~40% and then stopped, giving me this error: Code: To report this error, please provide: java.lang.IncompatibleClassChangeError at com.skcraft.pbinstall.SetupUtils.close(SetupUtils.java:40) at com.skcraft.pbinstall.tasks.ZipExtract.execute(ZipExtract.java:92) at com.skcraft.pbinstall.tasks.Install.execute(Install.java:74) at com.sk89q.task.Task.run(Task.java:156) at java.lang.Thread.run(Thread.java:680) It'd be awesome if someone could help. Thanks!
Playblock is already installed on the client so the problem is playblock shares class files with playblock making it incompatible with itself. In other words you are installing the same mod twice.
I am not running the actual client, I am running the same minecraft on the MultiMC client, because my computer doesn't let me backdate to Java 6, which is what the SKcraft client requires.
