The version of TSLPatcher you have included with the bug fixes option is outdated, and this is causing an issue in the Taris Cantina Dueling scene. Basically some of the scripts have a "+" at the end of them, and the TSLPatcher is removing those from the script names, which will break the dueling quest (the Gerlon fight is unable to start). If you grab the TSLPatcher included with the community patch it will fix this issue.
Not to be all RTFM about it but the TSLPatcher is not arcane technology, if you follow the instructions it will work.
If you're using Workshop mods, don't. If you're copying files manually, don't.
If the patcher is actually returning an error message, then I want to hear about it.
