invalid or corrupt jarfile

[WallaceHart]

Hello guys, I installed java and opened the file with it but now when i'm trying to install the game it says ''invalid or corrupt jarfile''. Do you know any fix to that? Maybe it has something to do with the fact that the when i downloaded the file it said this type of file can harm your computer. Any help would be greatly appreciated. Thanks!

In case you have installed Java it should be enough to click on

on the top of this page.

Java, like everything over the internet, is vulnerable to attacks. Don't worry, that had nothing to do with it. It's a warning, and nothing else. You just got a bad download. Open the Java options. Under the "General" tab, find the "Temporary Internet Files" section, and click the "Settings..." button. A dialog box will pop up. Click the "delete files" button, and make sure the "Cached Applications and Applets" box is checked (should be checked as default). Download again, and things should run now.

The method of distribution doesn't have extra file verification built into it, so files can be corrupted when transferring over the Internet and your computer won't know it. It's suggested that if you're on WiFi or other wireless technology that you use a wired connection to connect to the Internet if possible, or to use a different WiFi network.

The autohaven.jnlp is only a set of directions on what to download from where. You shouldn't need to download a second time if you got this error, but it won't hurt if you save it again from the website, either. If you keep getting the error message, I suggest you either plug your computer in via Ethernet instead of WiFi, find a different router to connect to (in case you're using public Internet or a connection at school or work), or reset/restart your router or modem that you use to connect to the Internet.

Worst case scenario: you have hardware issues you should have checked. Run your operating system's maintenance utilities. On Windows, this is Scandisk and Defrag. Open File Explorer, open "This PC" right click your primary hard drive, and select "Properties." In the Properties window, select the "Tools" tab. There should be two options. One will be "Error Checking" and the other is "Optimize and defragment drive." Run both of this in that order. (Note: Error checking will require administrative access to the drive. You may need to provide the admin password or log out and back in as administrator to perform this.) These both usually run in the background when the computer isn't being used, but sometimes you have to run manually. If either of these steps don't work, you may have other problems that may need diagnosis.

Please please help me aaaaa. I tried doing the error checking. Defragging I couldn't cause that program for it had to be installed? And it said it cant error check unless I schedule it for the next time my PC turns on. Now when I restarted my PC it's stuck on this Grey screen, unmoving and slowly heating up the battery. What have I done?!?!
