to try someone again in a court of law (= examine them to find out if they have committed a crime or not)

The original jury could not come to a verdict in the case. The defendant was retried several months later and convicted of the crime. 最初的陪审团未能对这个案件作出裁定。

to try to do something again because you have not been successful the first time

Don't worry if you make a mistake; you can always retry until you get the result you want. 如果你犯了错误，不要担心;你可以随时重试，直到获得你想要的结果。

If that doesn't work, retry with a different payment card. 如果不行的话，用其他支付卡重试。
