Someone on the PCA forum may well be able to help you, abut for problems specific to Corel Draw you can also try the Corel Open Forum. Make a note of this address for future reference. I found them helpful:
Sorry I cannot help on this one. I don't have XP. Installing the fonts is fine, but be wary of adding too many. 400 or 500 fonts is enough, more than that may slow down your system and cause problems.
