Lost my Java projects while sharing with RTC repository

How can I recover my losses? I'm using RTC 2.0 client for Eclipse.
I was sharing Java projects into an RTC component.
During this checkin, RTC defined a change-set names "sharing Projects" or something similar.
During the check-in, which seems to pour too much data into the server, I have canceled it using the "cancel" button.
All projects now changed status to be shared into that repository.
I have not delivered this change set, it was still in my stream.

I than started checking into this change-set the un-checked parts, yet all these tended to fail due to some server error that I have not recorded.

I decided to cancel the change-set, assuming I will set my workspace back to square one - that is: all my projects still intact, yet not shared any more.
I could than do the process a bit slower and more carefully.

Yet, the result has been that all these projects were deleted from my workspace and my file-system.

I called upon the RTC manager who could not find any traces of this in the server. It meant that server did not keep any records or content of any of my 1781 checked-in files.
My client deleted everything as well. The RTC manager could not find anything on my machine as well.

I am asking if anyone has any ideas how to salvage my losses.

I have - at least - learned that I should have made my own backup copy on my machine before attempting RTC backups. I am not doing that when I run TSM backups.
I need to trust this tool a bit more before using it again.

Many thanks,
- Uri

Thanks for your answers.

1. I did "Discard" on the change-set, not delete. I expected it to be cancelled - meaning undo the sharing from start.
2. The projects are gone from the workspace - so I cannot see any history for any of them.
3. When looking for chagne-sets, I do see a "remains" of a change-set with no name and no content to look further.

Hey Uri, It sounds a bit like your stuff is lost for good.
