I hope to uninstall TI v9.0 and then install the upgrade to v10.0. But I have read several threads in this forum that tell horror stories about Registry or other problems. Is it sufficient for a clean uninstall of v9.0 to just use Control Panel>Add-Delete? And just go from there to installing v10.0? If not, what else should I do? Please give me step-by-step. I am a beginner and I DO NOT KNOW how to edit my Registry. I am afraid to touch the Registry. Maybe I should just keep using the v9.0 I have, and forget about upgrading to v10.0. [And ask Acronis to refund the fee I paid to download the .exe file for installing the v10.0?] What do you think?
