Blob loaded but unable to be viewed.

Question

Hello friends
I have a peculiar problem, maybe you can help me find an answer
I have an application that uses blobs on my local machine. I have a hosted service provider who has a large database and offers a workspace that can be used by me. I am trying to load my application data to this hosting site.
We used the exp utility to send the data over to the hosting machine. The data is imported correctly at the other end and looks like the blobs too.
For some reason the application is not able to show the docs that were stored in the blobs.
My friend on the appshosting side checked on our database, and found the BLOBs did come over from the last import. Not sure why your application is not picking up the blobs.
Here it shows on the hosting database ECM_POLICY to prove that the docs came over. But the application doesnot show the policy document when you click on the link to the doc.

Would anyone be able to tell us why this could be happening
Thanks

A blank page is usually solved by performing a power reset of the router.  Also, you may have to reboot all PCs as well after the power reset.  Since this is a problem on all PCs, it's likely a router problem unless you haven't installed network adapter drivers on any PC after the Windows 7 upgrade.
If a power reset doesn't work, you may need to perform a factory reset using the reset button on the back of the computer.
