Issue of Missing folders in BOXI R2 while scheduling

In our BO XIR2 environment, we used to schedule reports using the administrator and publish them in respective folders in CMS. All of a sudden one day, when we wanted to schedule one report, the folder list in CMS disappeared. From the desktop client, when we clicked on export / import repository, it did not list the folder list. In fact the root folder itself was disabled. It was surprising since no changes were done. After rebooting, rechecking the server settings and checking in the testing environment, problem still persisted. From Infoview we were able to view the folder list and the reports scheduled. We then tried to login from a different administrator user and there the folder list was visible!!! our activities are resumed, but still do not what happened to the administrator. Must be something to do with rights. We have raised this issue with BO support. Will update with the reasons..
