I have the same problem. I want to try the trial version as I was a big fan of Acid many years ago. However there seems to be no way to register for a registration code. 😡
Same loop problem and tech support here.. BUT FOUND THE SOLUTION see below
Hello,
This problem can sometimes occur when a trial version has been previously installed and activated.
In order to resolve the problem, please do the following:
- Close the program if it is running.
The next step will require you to make changes in the Windows Registry.
- Open the Registry Editor.
To do this on Windows, press the Windows key and R together on your keyboard. In the window that appears, type REGEDIT and press Enter. If prompted, allow the program to make changes to your computer.
- In the Registry Editor, navigate to the following directory:
HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > Sony Creative Software > Acid Music Studio> [Version Number] > License.
Right-click the License folder ONLY and select Delete. If prompted, confirm you wish to delete the folder. Once the folder has been deleted, close the Registry Editor. Launch the program again. You should now be prompted to enter your serial number and the 'activation loop' will be resolved.
