you've gotten yourself into a pickle. to get d7x to run again, you need to delete the registry key HKLM\Software\d7xTech\d7x and then run it from a folder on the desktop or anywhere on the local drive.
as far as safe mode, if you selected the Safe Mode w/Networking mod in d7x, realize that mod keeps you in safe mode until you run the removal mod for that.
In d7x look for Remove Safe Mode w/Networking mod, and if you don't see it in your lists, you can find it/add it to the malware tab lists by searching d7x internal functions for "safe mode" (right click in the malware lists and choose to add a custom app or function).
