Ouch! Lost the job before I got it

Everything was set! I had been interviewed first by the recruiters, then I met the company twice, and negotiated position and conditions. Everything was great and they seemed very eager to start and we had even started to discuss what projects I should take one. They had sent me a contract to sign and I was looking through it during the weekend. On Monday I participated in a conference by the Swedish Export Council about doing business in China, and during the afternoon I was supposed to come and sign the contract. During the conference the recruitment company called me and said that the company hadn't signed and that there was something wrong. When I called back later, they said that the company had probably lost a contract and didn't want to sign the contract. Ouch. The recruitment company said they had never had the experience of such an abrupt turn of events. If I had signed on Friday it would have already been set! SUCKS!!!
