Hey Alexandre,
More information is needed. What version of the TFS are you using? If it's not the latest version, then start by updating to the latest version and trying again.
Next, make sure logging is enabled in the config files.
Next, make sure no other instances of the TFS are running. If they are then the service will fail to start. That is by design. Only a single instance for the LimeLM product version can run on a machine.
