VPS Java/red5 help

[AsianX]

Ive read many pages ( google search ) most of which, confuses me more.
Can and if.. Java/red5 be uninstalled and reinstalled?
Reading down there is another option to install java/red5, but was unsure if it would conflict with whats already been done.

Also noticed other errors,warnings,info..

Any pointers, options, help .. would be appreciated..

The root cause of the exceptions is that a server is already bound to port 1935 (the "Address already in use" message). Stop any previous instances of Red5 before starting a new one.

Generally speaking, rebuilding and re-installing an application will overwrite old installs that are the same version as long as the files aren't in use and you install to the same location. Whether different versions are overwritten depends on the package. I don't see why Red5 should be any different.
