If something is changed on the PC used to run LightSpace/SpaceMan/SpaceMatch you will see a 'Protection Error' warning.
The 'Protection Error' warning will likely be caused by a hardware based change (new additional hard drive, graphics card, etc.), but could be a major Windows OS change, or due to changes to the LightSpace/SpaceMan/SpaceMatch software. If the 'Protection Error' warning is due to a change in the LightSpace/SpaceMan/SpaceMatch software the associated download information provided when upgrading the software version will infom you of this requirement, so please, please, always read the provided information when upgrading!
When the 'Protection Error' warning is seen you will need to contact Light Illusion to request your License Registration to be re-set.
You will need to include your license code with any request for a re-set, as well as information on why the re-set is required: a hardware change to the PC; a large OS Update; replacing an old PC, etc., as well as your name and email address.
Note: The License Code must be provided as text within the body of an e-mail, not as a picture attachment.
A license reset will be performed as quickly as possible, often immediately, but can take up to 24 to 48 hours, depending on location and timing.
