Frequent problems - please read carefully: 90% of the messages I receive regard these two questions:

1. License key not found / lost
If you did not receive an email after buying a license or cannot find the license, please do not use this contact form, but instead click here to get your license key.

2. Online activation not possible or other program issues
Microsoft crashed older programs with an update of July 1st 2020.
Please install the latest program version of your program from this website, they have been compiled with a later version of the .Net framework and will work.

If you have purchased one of my programs and didn't receive your license key shortly after, check your spam folder carefully - the message may have been blocked. The license key is sent to you within a few minutes after your purchase. You can always retrieve your key(s) by entering your email address here. If that does not work, send me a message via this contact form. Feedback of any kind or business offers are always welcome!
