I've now used 3 of 5 activations on the SAME PC. I am concerned when it comes time to filing my taxes, I will have no activations remaining to launch the product. After each recent TT update, I am prompted to activate my license. It appears TT is using a faulty method to detect PC identity and not recognizing PCs that already have a license activated. Reading msg threads, this seems to be a repeat problem for some users each year. Is there a patch or fix?
