Tasnam,

Alternately, you could give Continental a call and ask them to mail out your paper tickets. I just did that the other day with NW b/c the online booking system always issues an e-ticket whenever possible.

BTW, airlines can readily rebook you onto other carriers with award tickets. The only difference is that they often use FIMs (Flight Interruption Manifests) rather than simple endorsements.

But from what I have heard, this is actually to your benefit. A gate agent once told me that the common policy is, if the other airlines flight is overbooked, an endorsement only puts you on the standby list. With a FIM, however, the second carrier MUST put you on the flight, even if it means an involuntary denied boarding for other pax.
