Hello, I am using TheSkyX and a SBIG-STi guider with Windows 7 64 since 4 months without problem until now. During a session I got a timeout error 30007. When trying to reconect to the guider I got a SBIG driver not found error 30027 that I have since then. The CCDObs does not recognize the guider anymore (no camera could be found error ), the Graphic/Comm setup interface is set correctly to USB. The SBIG USB devices was marked unrecognized but now seems ok with a SBIG USB-64 Camera with Firmware pilot (see picture). I reinstall CCDObs and the SBIGdriver checker 64, I deleted all the drivers and reinstal them (see picture) several times without success. CCDObs is version 5.57 build 3NT. I just download the SBIG Driver checker, it is version 4.0 build 8. I did not find a newer version. TheSkyX is Version 10.3.0 (build 8908). Please help. Regards.
