[求助]Error(spcocd-553): Connectivity Server Error

我是用cadence16.6版本的Project Manager画的原理图。
问题1：在保存每一页page时，都会报错"There were 1 error(s) found. Would you like to view them?"。错误的描述是：“Description : ERROR(SPCOCD-553): Connectivity Server Error: Failed to open file 'E:\123BKP\worklib\123test\sch_1/123test.xcon' in write mode” 。
问题2：到最后执行Export Physical时，报错Error:PXL failed. Unable to package the design. Do you wish to view the pxl.log file?
