I just purchased SparkTrust PC Cleaner over the web. I didn't get a license number. Could you please provide me with it by e-mail?
Answers Informer does not deal with licence registration details. If you have any problem with the purchase, you should contact the seller of the application or the developer as it will be provided additional information related to this issue.
As Pete Clapp suggested, please contact the developer when it's about licensing or serial registration. Make sure to provide all the registration details used when you have purchased the product.
