Vista Help...Please...copy/paste help

I recently upgraded to Vista Ultimate x64 and I am having a very annoying problem.Heres the deal.....I have a data dvd that I burned awhile back while still using XP Pro,well today I opened it up to run an exe file and it tells me that I dont have apprpiate permissions to access or something similar...so ok?I then figure Ill just copy/paste to HD and it then says that its a read only file and I cannot move or delete.I then try to see if properties has a security tab and it does not,I am the admin and the only account.why cant I open or at least copy/paste this file,I tried to copy/paste the entire folder that the file is in and everthing but the exe would copy,what am I missing here,I have only been running vista for a coujple days now.Vista is fully up to date,all drivers are.
