求救，我的eclipse3.6.1安装swt-designer老是出错

各位大侠，我的eclipse 3.6.1安装swt-designer时，老是会出错，我是在 installing software中安装的，用的是http://dl.google.com/eclipse/inst/d2wbpro/latest/3.6 这个地址，开始还行但每次到46%时就不会动，我重试了n遍，还将eclipse，卸载了一回，过一会儿还报错
求解决，有木有？

这是错误信息，高手帮忙看看！An error occurred while collecting items to be installed
session context was:(profile=SDKProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
