Thank you folks, for all the replies in the previous entry!
Actually I have not solved the problem yet, as I could not enter Safe Mode nor Dos Prompt, so could not access the downloaded file that Chrisloup gave (thanks so much though!), or amend the corrupt dll file... :(
I am now typing these entries using the IBM Rescue and Recovery's Opera browser thinggy (which is a great, but very limited, blessing)...
But strangely, although I could create a new blog entry in Opera, I just could not reply to all your comments (or enter even Facebook)!?!!
In any case, I will be meeting Squido tomorrow to see how to solve this problem in person...
Keeping my fingers crossed meantimes, and hope this entry gets sent successfully too...
