Application has encounterd a problm

[Echo]

This is the error message im getting and explaination is below:
"Irth client has encountered a problem and need to close. We are sorry for the inconvenience".

Irth is a game I have been playing with no problem til yesturdays patch. After the patch I attempted to log into game and after I started the game launcher and it updated files I got the above messege. The head developer of the game thinks its a os problem and suggested I "restore" to an earlier date (before patch) I restored my comp as directed and after hours of patching I still got the same above message.  I have error messages in event viewer and when the head dev looked at the pic I took of the event viewer he said it didnt tell him much. My bf is about to reinstall the whole OS, but before we do that I thought I might be able to get some help here.

Firewalls is permitting Irth client

I uninstalled the game and reinstalled it also, with the same results.i have a western digital 80gb 7200 rpm/8mb buffer

OS formatting is the last option.

A simple try might solve your purpose  8-)

Uninstall and reinstall the game.  

Keep us updated.

That was what I did first thing...I reinstalled the game and still got the same error message.

today I took out the Windows xp home edition disk to reinstall the os. On the main menu the disk gave me the option to install os or Repair, so I chose repair 1st. After repairing was done I tried logging into game and got the same error message. So I felt I had no choice but to reinstall the os.

I preceded to install the windows home Xp everything was going fine until I got to the "partition" part. It gave me a choice....install on Ftps (i think, it wasnt an FAT) or unpartition. I 1st chose "unpartition", next screen told me that it was to small to install onto. So I chose FTPS (that was my only other choice) The next screen told me that if I continued to install on FTPS partition it is posible that I would be installing another operating system and that the operating system would become unstable. Well the words "unstable" and "2 os" made me back out of the whole process. I have done this before but I forgot what I did on the partition part. Should I continue and ignore the message about 2 os and unstability. I dont understand why there would be 2 os there to begin with. Im installing an os which I thought would wipe out the old os. Help if u can...
Thank you....
