Your review is quite unfair, I would like to clear your queries yet again :
1) Altering php files : Please understand that one cannot overwrite Virtuemart template files (These files are not always common and its code is completely different depending on the VM templates used. It is only possible to use embed code to display the timer wherever needed. - This is a programming limitation and not possible through creating any config files as much as I understand)
2)The timer is not off even by a second - Infact The time is not created by the module itself, it is rather fetched from the Virtuemart discount parameters you created within the product discount list in Virtuemart. If there is such a problem, then it lies within your VM/Joomla misconfiguration on your webserver.
3)The module when purchased is immediately delivered - I did clearly explain that our purchases are instantly delivered to your paypal registered email address. This does sometimes get filtered in your Junk/Spam folders within your email clients/ spam protection engines. Besides that we do respond back to all our customers within 12-24 hours (considering timezone differences). - I did send you personal responses to you myself within 1 day I checked in logs.
I believe it is a misunderstanding on your part.
