CDR file takes very long time to open


I am having trouble opening up cdr files as they take very long time to open (around 20-25 min per file of  5-10 MB).

Following are my system specs:

>Intel Pentium 4 - 3GHz, 2 GB RAM, 

>Windows XP SP2

>Coral Draw X3 installed

I have already tried deleting unnecessary fonts, views and color styles. I also restored corel to factory defaults (using F8 key at startup) but some cdr files still take a long time to open.

Any help is greatly appreciated.
