when I try launching msn messenger (any version) error msg saying Application failed to initialize properly (0xc0000005). I'm Using Windows XP Service Pack 2 with Dell Inspiron 6400. Already tried several options such as: remove/reinstall; registry cleaner; spyware and anti virus scan;checked firewall settings for full access and others....This problem suddenly started about 3 months ago. Prior to this MSN messenger (8.0 ) was working fine. No changes were made to my pc prior to this problem.
