hallo? It would only take a couple minutes if someone would run a checksum on thier copy of the trial.
I don't want the trial and I'm not going to download it for you.
Check it yourself.
I had to laugh reading this thread and seeing it tagged as having 1 "correct" answer available and 2 "helpful" answers available. Some people can't resist posting even when they have absolutely nothing helpful to contribute.
Anyway, Ooll, here are the MD5 checksums - hopefully they will match what you have:
ProductionPremium_CS5_LS7.exe = 2224403328920192f9e06dec9903644c
ProductionPremium_CS5_LS7.7z = 355496e3db52531620694a6f6a0ea79c
My checksums matched! thanks.
