Normally TeX waits for user input, when an error coccurs. Because user input is not possible with the current version of TeXnicCenter, TeX would hang up. To avoid this, TeX has to be started with the "nonstopmode"-option on its command line. (It is called "nonstopmode" with the MiKTeX distribution - it may have another name for other distributions.

Take a look into the online help of TeXnicCenter. The Topic "TeXnicCenter > Configuration > Output Profiles > Configuration > Manual Configuration > The '(La)TeX' Page" describes how to change the command line passed to the (La)TeX compiler.
