Ooh, that stinks.
You can try Restoring your system to a Restore Point from before you removed stuff. To do that:
Start -> All Programs -> Accessories -> System Tools -> System Restore.
Then choose Restore my computer to an earlier time. You'll see a calendar, and some of the dates will be bold. Bold means you can restore your system to that day. If you go back, all the programs and stuff you uninstalled should come back.
Yeah i was thinking of that but i thought the restore dates where from when you created them and i havent created one in AGES.
