can u fix this?

without further information, such as a latest.log or at least confirmation that the issue occurs with just hammerlib installed by itself, then no, zeith will not be able to fix this

just install the hammerlib ALONE on forge 2855 and you will see that the game startup freezes at fl stage 7.
and this is what the logs say:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
