Problem with Fs Real Time

I really hope that someone can help me with this since I really like what Joshua has done to keep Fs2k2 in coorect time.I uninstalled the previous version to install the one uploaded yesterday, and when prompted to delete any unused common files I pressed yes. Now when I try to install the new version I get an error message "uninstaller cannot find ...systemcore.dll". Has anyone noticed this one before and if so what should i do to fix this. I even located a copy of core.dll in a temp folder and pasted it in the system folder but I got the same error message.I would be grateful if someone could provide me with an answer because I fear that this might affect other installations as well.Thanks,Vassilis
