About importing the VirtualBox Base VM

[akacd]

I tried to import the Tuxedo Samples.ova to vbox.But I always get this err.
导入虚拟电脑 D:/VM/TuxedoSamples/parts/TuxedoSamples.ova失败.

Could not create the imported medium 'D:\VM\TuxedoSamples\Tuxedo Samples-disk1.vmdk'.

VMDK: Compressed image is corrupted 'C:\Users\duchao\Tuxedo Samples-disk1.vmdk' (VERR_ZIP_CORRUPTED).

返回 代码:VBOX_E_FILE_ERROR (0x80BB0004)
组件:ApplianceWrap
界面:IAppliance {8398f026-4add-4474-5bc3-2f9f2140b23e}

I'm using the lastest version of vbox which is v5.1.0.

I also tried to google around,try to unzip it to a ovf file and vmdk file .And importing the vmdk file also failed.

Did you verify that the download succeeded correctly by comparing the checksums?
