??? 一顿google之后，关于myeclipse集成安装之后出现这个bug的解决方案很少，官网还上不去，汗！
?? 最终通过翻墙网站到官网，找到了一篇类似的问题，但是全是英文，隐约看到好像是跟授权相关。
?
? 马上又google了一个myeclipse 8 的注册码：
??
LICENSEE=LauChengLICENSE_KEY=YLR8ZC-855550-6765665204902409
?
安装注册码之后，重启myeclipse，问题解决，哦也！
1 楼 grandboy 2010-01-16 我以前用7.5的时候在使用一段时间之后，发布myeclipse里面只有一个subscription菜单，我以为需要我再次注册呢，不好意思和楼主同道中人，都是D版。结果怎么搞都不行，我重新注册之后，它也告诉我注册成功。就是其他像模任何菜单都不出来。
