@ Mr. Durian: I think there are some versions already patched to 1.5. I bought my version of R: TW in mid-2005. I tried to install RTR Platinum 2 months ago and did the whole routine (like U about 5 times). Not working...CTDs all the time. Then i just installed my vanilla version and RTR over it...BINGO...RTR Platinum working flawlessly.
