求救～～～BlueJ不能开启～～

二十四味

之前在自己的电脑里装了BlueJ，用的还好好的。之后有段时间没怎么用了，之后想要开启的时候就总是不不行，出现一下对话框。
BlueJ was unable to create a virtual machine(VM) to execute project-s. This is a serious problem-you will not be able to
create objects or execute methods without solving it.
Usually, this problem is caused by specific network settings on your machine. BlueJ uses TCP/IP and sockets to achieve the creation of the VM. The most common cause for this is an overly restrictive firewall that does not allow connections from your local host. Switch off the firewall(if you have one) to test this. If this solves it, try to find a firewal setting that allows connections fromm localhost.
Other possible causes are incorrect network settings. Check that TCP/IP is set up correctly check other networking parameters.
If problems persist, ask for help。。。

防火墙是开了关了都试了，重装也都试了，jre什么的也装了，都还是一样的问题，请问个位知道如何解决这个问题吗？如果能得到你们的答复，那就太好了～～{:5_360
