Got sudden problem with SQL DB!!

[Symbian Galaxy]

Hello,

I was installing a Hide hack resurrection [expanded] version, i have uploaded all files came along, then started editing the files... !

Once i finished editing the files from the FTP, i gone to edit the template bits.
But, when i went to the style manager to edit the templates of the skin, it shown me a DB error.

I was shocked, and i was wondering what the hell did i do
I tried to get into other admincp section, but i get the same error there too.

So, i got afraid and thought to revert all the uploaded files and edition i made to the php files.
So, i did reverted everything back to normal.
Now, i get the error as :

Hide hack resurrection not installed completely.
Please read the readme.html file.

Thats it. now, i cannot even login to admincp.
it shows me the same incomplete error while logging in.

If someone came across this sort of problem, then please care to help me out.
And anyone else around knows the solution to get the board back to normal would be appreciated.

Thanks in advance!
