you can bypass the license expiring by using nirsoft runasdate.exe to set the system date to a date within the valid license period.
Also why does this abuse the logged in users Documents folder by placing two folders containing data files in the Documents folder?
C:\Users\WINDOWSLOGINNAME\Documents\Coolmuster files\Coolmuster SignPub\Log
and
C:\Users\WINDOWSLOGINNAME\Documents\iStonsoft\ePub Editor\scratchpad
Who is iStonsoft? are they the original authors or another name Coolmuster pretends to be to the western world?
I also note that unlike most other coolmuster products this DOES NOT SHOW AN EXPIRY DATE ON THE LICENSE so might not be an expiring license! Using runasdate I set the date to Jan 2028 and the program still reported as registered so it’s a good bet this is a lifetime license not a 1 year expiring one… just wish it was not such a Documents folder polluter!

Hi,
The giveaway duration has recently been changed by Coolmuster, and it will be back soon.
I have used the Coolmaster software PDF to Epub Converter, and it is a great program. Because of that, I had every intention of purchasing the program when the ‘Giveaway’ expires. However, I have tried to obtain some more giveaway software, especially this latest one, Signpub, but Coolmaster never give enough time, and the giveaway is over after just a few hours, and that is too much of a tease, so I am looking for other companies that do similar software – disappointed to say the least.
