I havent seen it posted and I've seen read many times about the trial version of things. Well heres your solution. Most of these trial versions that have full access but limited use can be fixed. They have registry stored that tell how many days or whatever you have left, which can be deleted. I have not come across something this does not work for and I use it all the time for my speed hack.
1) Start>Search>Search for "Regedit" (located in C:/Windows)>Open
2) Alright the codes you are looking for are stored under either HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE, go to software, and finally find the trial program you are looking for and look for a certain value.
Ex. I will be using game speed changer because is my favorite speed hack and its easy to change. Follow step 1 and go to HKEY_CURRENT_USER>Software>Game Speed Changer>gsc>Registration Info, now on your right you will see a "days" value. Delete it. Congratulations you now have figured out how to have a permanent trial.
If you have any problems let me know, as I am fairly new I will help to the best of my extent and dont just want to be a leech.
