Recover earlier Version of a project

Hello Creative Cow
i have quite a big Problem on my Hand right now!!

i just switched to After Effects CC a week ago

i had this big project which i had to prepare for a client to change some text elements
so i wanted to reduce the whole project to just the comp the client needs to change

i chosed the one comp that was needed for the client - went to "collect project" and said it should be reduced

i thought AE would create a reduced copy of the current project
BUT instead of doing so it just reduced the project i was working on not making a copy!
now im left with just this one composition in my AE project and it seems that work of more than weeek is lost

is there a way to restore an earlier version of my project??

thanks for any kind of help in advance!!

first: thanks a lot for the super quick response!!

i just checked, but no; the auto save option was not turned on (i did turn it on for not running into anything like that ever again!)

are there any other possibilities to recover an earlier status of a project?

sadly not...

ok, seems that i have to wrap my head around the fact that a big chunck of this project is lost then

gladly the main animations were already rendered out and by now its only some little animated text comps that i have to redo - i just hope there wont be any changes requesting the main animation...

for next time: collecting and reducing a project does NOT create copies?
so, if i have to send out a reduced version of a project, but still wana keep the big one to myself, i have to make a copy of the AE project in the finder and then reduce the duplicated version of the project in AE? (because i thought recalling after effects CS4 doing a copy automatically of the current project when i collected and reduced a project)
