Hi. Thanks for your reply.

I have tried the first option you suggested already, with no success.

I have since deleted Real Player from my pc completely, and have noticed that the preview movie icon is now showing as Windows Movie player underneath it.

I then tried deleting it from doing a pc search outside of Limewire, (making sure that LW was closed down beforeheand), this again, didn't work.

I am now going to check out the link you sent me, I hope I can find the answer here, I will let you know.
Thanks again for your help.
If you or anyone has any other ideas then please can you let me know.
Thanks
