As a student I used an eMac - which was sufficient till I graduated. I have recently upgraded to a MacBook (and Leopard), as such I have begun the long process of transferring files, etc. However during moving from student accommodation have lost a majority of my installation disks.

I have moved Photoshop CS, etc with no problem but now when dragging Dreamweaver & Flash into my new Apps folder and launch the program I get an error saying invalid.

Is there anyway around this without having to splash out on a new copy of the software (as you can imagine - after buying a macbook and being an ex student with mounds of debt i don't have much of a disposable income).

You help would be much appreciated
