All documents registered before today have now been disabled, so you wont be able to open them. For the new documents, we are now using the software I had created for it, which is also the service I provide at www.freedocumentsecurity.com
I had this software created because no other software had the features needed. However, the only documents that have particularly sensitive information is the Uber documentation, but even if they leaked it wouldn't be a major issue. But still it is better to have the security than not.
To request access to any new documents, see http://www.genuinewinner.com/software.html
