*cough* The error was spending money in the first place. *cough* I can't read that, but one likely cause of errors at that point (blank window) is a graphical problem. What kind of video card do you have? Maybe make sure you have the latest driver. If you're trying to play RO in a windowed version, try it in full screen instead. If you're playing in full screen, try windowed. Try turning all the graphical settings to their minimum, disabling sound, etc. to see if some setting might be wrong. Try looking at RO message boards to see if anyone else has that error, very likely someone does because RO is always laden with errors. I'm not playing beta this time, but I played before, and people always had a wonderful variety of error messages for a wonderful variety of reasons.
