You better don't forget any spaces, else it won't work. That's what the ':' are for.

Here some hints for the clueless:
After you decode the above you will have a sentence followed by a sequence of decimal numbers, then a space, and then another sequence of hex numbers. The next step will be to decode the two number sequences separately, and then combine the results to get the password. Sounds easy, doesn't it? Oh btw. The above key is only for the first encryption, so forget about it afterwards.
