Do you not have any crash logs, any error reports? Try checking the technic folders to see if any are present.

Furthermore, ensure your antivirus is uninstalled, as they usually prevent the launcher from running properly for the first time a pack runs.

Finally, 32bit Java is known to be quirky, so ensure your java is 64 bit and not 32 bit
