Cannot download card from Hyperledger Composer Playground - hyperledger

Question

I'm trying to export my Network Admin card from the Playground UI, but the export icon is disabled. In addition, I see the following error in my Chrome console:
Error: The current identity, with the name 'admin' and the identifier 'ddae16d6f23947e9349627051b8ca5933cef53d2918f52295352d7dd24cdabcb', must be activated.
How do I export the Network Admin card from the Playground?
Here's the full Firefox log:

Answer 1

This is the answer I got on GitHub:
The reason that the export is greyed out is because you are using the
bluemix staged Playground that is in the 'web-connector' mode. In
order to meaningfully export a business network card, you will need to
create a connection to Hyperledger Fabric. The steps you outline above
will not create a business network in Hyperledger Fabric, but within a
web connector.
If you follow the developer tutorial
(https://hyperledger.github.io/composer/tutorials/developer-tutorial)
you will be taken through the process of creating a (local) Fabric,
from which you can connect Playground and export business network
cards.

Answer 2

You can create the admin card via composer-cli.
composer card create
-p connection.json
-u PeerAdmin -c Admin#org1.example.com-cert.pem
-k 114aab0e76bf0c78308f89efc4b8c9423e31568da0c340ca187a9b17aa9a4457_sk
-r PeerAdmin -r ChannelAdmin
Add connection.json file as following:
{
"name": "fabric-network",
"type": "hlfv1",
"mspID": "Org1MSP",
"peers": [
{
"requestURL": "grpc://localhost:7051",
"eventURL": "grpc://localhost:7053"
}
],
"ca": {
"url": "http://localhost:7054",
"name": "ca.org1.example.com"
},
"orderers": [
{
"url" : "grpc://localhost:7050"
}
],
"channel": "composerchannel",
"timeout": 300
}
The certificate file can be found in the signcerts subdirectory (fabric-tools/fabric-scripts/hlfv1/composer/crypto-config/peerOrganizations/org1.example.com/users/Admin#org1.example.com/msp) and is named Admin#org1.example.com-cert.pem.
The private key file can be found in the keystore subdirectory. The name of the private key file is a long hexadecimal string, with a suffix of _sk, for example 114aab0e76bf0c78308f89efc4b8c9423e31568da0c340ca187a9b17aa9a4457_sk.
