Current: corel Draw Graphics Suite X5 SP2OS Vista 64 bit SP2 one user. with admin privileges Updated X4 to X5 in May 2010 and then upgraded to SP2 when released

Occasional crash and slow to open all services. I use Corel every day, cannot live without it.Runs days with many files created  with no restart.Then during day of 20/May/2011 A new file saved could not be opened. ( silent no warning ),

All Old files Open OK, templates open OKany new file made since cannot be opened. No Known install or updates on the day or days prior to issue.Ran repair. Issue continued unchanged.Eventually restated with F8. But new files again not opening.Updated  user default settings no change with issue.I did notice long delay in saving new file longer than normal.

Restarted Corel Draw, which now Hangs on stat up ( Loading users settings stage )Restarted machine same problemUninstalled X5, Restarted, Re installed X5  Install OK.
