Hey everyone!
I managed to fix the problem when guild 2 warns of wanting you to put in the original cd in the drive when you instead want to start with your image (*.MDS) file.
Go in to your contolpanel and click on the administration tools.
Next click on "computer management or systemmanagement (have a swedish windows and its hard to translate to english, but click on the icon with a blue computerscreen)
Next you need to open the discmanagement (just under the defrag icon)
Here you need to manually change your Deamon Tools virtualdisc and your original disc drive letters.
Lets say when you try to start guild 2 and the program says, "put in the orginal disc in drive E:" (E: is your normal cd/dvd reader)
Then you need to first change your normal reader to for example I: and at the same time change the deamon tools virtual disc drive to E:, after this the game will autostart to the normal menu and you need only to click on play or "spielen" to get the game started.
This will not work all the time and the order you need to do this may not be the same as mine, I needed to do it one way with 1.15 and an other way with 1.16 . But IT WORKS...just try and change the driveletters at the same time as you start the game and try also when the warning apeears that says (put in the original disc in "blablabla")
It may also be needed to change the drive when the warning appears and click on "retry" when the driveletter have changed to the one the warning wants you to put the original disc in. And at the same time when the menu autostarts click on "play" or "spielen"...However, try different scenarios and the game will start, it works for me ....
Hope you'll get it to work now
