How to reinstall CD Sequencer.
To reinstall you need the zip file with the demo version and a recent copy of the files in the CD Sequencer folder (in the Program Files folder). You can download a copy of the demo version but it is wise to keep a backup copy because the version that you have registered may not be available anymore in the future.
When you're hard drive is erased or if you bought a new PC then follow the procedure for installing the demo version and then overwrite all the file in the CD Sequencer Folder with the files from your backup CD. Just reinstalling the copy of the CD Sequencer folder without reinstalling the demo version will not work because you will be missing the runtime libraries that are installed in other folders. If you use more PC's then you may install CD Sequencer on each of them but only one may be used at a time. Otherwise you should register more copies.
If you didn't make a backup copy or lost it, then you can request a new copy but it will cost $10.00. I keep a list of all registered users.
