Touble with Nokia PC Connectivity SDK 3.0,,,Pls help!!

[robbie_brar13]

Can anyone please help me to install nokia PC suite for 6600 on my PC. It was working fine b4 but when I tried ot install something on to my fone using the suite, it got screwed.
Now I have uninstalled and reinstalled Nokia Suite for almost 50 times(no kidding) from the CD ROM and the nokia sites(US, Europe, Asia, etc) still cant run it.
When I install the Suite I see the Mrouter in my taskbar and it also gets connected with the phone, but when I open PC Suite it shows that the phone is not connceted. I dont know whatz going on and when I uninstall the PC Suite, the connection manager icon was still staying there in the Taskbar. It wass not going away. Somehow I got rid of it by deleting the file, but Nokia PC Connectivity SDK 3.0 was still showing it the add remove programs and when I tried to uninstall the program, it was not unistalling as the uninstall sheild was stopping in between the process.
So I uninstalled it manually and got rid of it from the add/remove program box,then tried to install PC Suite again but I got the same problem i.e. PC Suite was not recoganizing the connection where as the Mrouter was showing that the phone(6600)is connected.(btw everytime I installed the Suite it didn't asked me to install the SDK)
Then I downloaded the Nokia PC Connectivity SDK 3.0 from this site(forum Nokia.com) and tried to install the SDK manually and got this message:
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the exsisting version of thsi product use Add/Remove program on the control panel.
C\:Windows\Downloaded Installations\{887CA364-68B1-4FF9-9D6E-067CEF54E894}\Nokia PC Connectivity SDK 3.0.msi

Can anyone please tell what's going on and I dont have any clue what next to do. I did everything possible but all in vain. Now ther is no SDK in add/remove programs but I am still getting the above message. This is my last resort and my last cry.
I was big fan of Nokia but now these problems are turning me away.
