MB STAR F/Xentry_SD4_2015.09/DAS-000001-s013.vmdk failed error

I use EXTERNAL HDD. It is strange here, today i open the software and it give me this prompt:
Xentry_SD4-2015.9- VMware player
The operation on file “F/Xentry_SD4_2015.09/DAS-000001-s013.vmdk” failed.
If the file resides on a remote file system, make sure that the network connection and the server where this disk resides are functioning properly. If the file resides on removable media, reattach the media.
Select retry to attempt the operation again.
Select cancel to end this session.
Select continue to forward the error to the guest operation system.

for this problem, it is caused by the following reasons:
1) you use this HDD on other PC. and forget to turn off the star software
2) your win7 system does not support. Or our VMWARE displayer cannot run our VMWARE
3) VMWARE is broken.
if software is broken, please send it back to us, we remake the HDD for you
