an unexpected error has occurred on the singularity reactor

every time i que for the singularity reactor i get an unexpected error has occurred and it will not allow me to re join the game until i have either been kicked from the party or until the group has completed the trail. every time i try to log back before one of those has happened it will go to the load screen and an unexpected error will occur again and again sometimes keeping me offline for hours at a time

May have some corrupted data. With any luck, you are on Windows and may be able to recover it by running chkdsk:

That guide details both fixing errors and scanning/recovering bad sectors. May not need the /r switch (sector scan/recovery)--just the /f switch may suffice (fix errors found in the file structures and such).

Using the /r switch can take a long time, and should really only be necessary if your drive is getting a lot of errors. Windows is notorious for knackering up things in the file system over time, and often needs a little tightening up here and there---especially if the system rarely gets shut down. There are some basic housekeeping rules that need to be run in NTFS from time to time during shutdown/startup.
