I bought Schweser Essential package and opted for downloadable Schweser Pro. My hard disk crashed. I tried every possible way for recovery and managed to recover some. However, Schweser Pro does not work. (Partially my fault because in the first recovery I tried to restart it with the registration code and it crashed again) Now, it gives message that I exceeded the allowed number of registrations. I wrote to Schweser, no reply yet. Is there anybody around with similar experience? I really do not want to buy Q bank again.
