First thing to do is not to label HELP. Make some discription to problem.
Is this your old program or the free download version?
Is this the new version that does not need activating? If not, then it might be worth downloading and installing that version.
But if it is freezing while opening, that could be a bad font file, or possibly a plugin. If that's the case, then reinstalling won't help. Have you added any fonts lately?
