I know this isn't a programming question, but there doesn't seem to be a category for software questions on this forum... maybe I'm not in the right place, but if anyone knows anything about software and windows, etc, maybe you can help me with my problem, or lead me to a place where I can more appropriately seek help for this issue: I had a software developer create a program for me to help with twitter management, and it works just fine on my Windows 7 computer. But I need it to work on my VPS which I believe is running on Windows 2003. Well, my software developer said he would make it work on my VPS, but he has been awol for 2 months and I need it done within the next week or so. It's becoming a very urgent matter... Does anyone know what I can do to make this software (that works on Windows 7) work on my VPS, Windows 2003? Most of it works, but the part where it has to connect to a Twitter app does not work. It says: "Whoa there! The request token for this page is invalid. It may have already been used, or expired because it is too old. Please go back to the site or application that sent you here and try again; it was probably just a mistake." I let my software developer know and this is all the information I got from him: "It seems that the libraries are incompatible with the VPS server, so I have to look for alternatives for it." He said he would fix it when he got a chance, and I've messaged him every 2 weeks with no response for almost 2 months. If anyone can give me any info at all that might be helpful, I would greatly appreciate it!
