security valid ID

[imark]

I try to make security by the User ID. I've choose the Validation Type "User ID" and clicked "Generate registration code".

But it wrote me that I "must provide a valid user ID". I tried a lot of variants, but I can't understand what it wants?

So what is the valid ID and how it must look like?

The user ID is shown in the System Information dialog in iSilo. See user ID quick reference (http://www.isilo.com/support/publishers/userID.htm).
