I am having the same problem with AnyDVD 126.96.36.199. I purchased the software on July 11, 2005 and have been using it and updating it without problems since then. When this version (188.8.131.52) installed, it told me that my 21 day trial had expired. I then ran my key which told me it was registered but still got the same message. I uninnstalled the program and removed the key info. I then installed the program, ran the key, and got the same result (Expired Trial Version). At this point completely removed AnyDVD, eliminated all references to AnyDVD in the registration database and tried again. Since then I have read all the posts on this forum dealing with AnyDVD and tried many times following the steps outlined in this thread without success. It sounds like writing to Slysoft will not help. Please advise. Thank you.
