打开CES时报错

Note: Import failed.

There was en error importing the design.CES is exting.For further information, look at the error log file  D:\Mentor_Projects\pwb90020\\Ces_dxdesigerCDB.log

把LOG文件贴上来看看Ces_dxdesigerCDB.log

Note: Importing from project 'D:\Mentor_Projects\pwb90020\pcb\pwb90020.prj'.
ERROR: Error extracting jobprefs database \Layout\JobPrefsDB.jpf

先做好备份。然后把CES相关的东西都删除了（文件夹搜索CES,删除)，重新打开看看。

小编用的是EE2005以下的版本吧，它们的CES就会经常报错，有时候可以忽略的，看具体情况。
