For your case, it is a known issue. Your subscription is going to expire on October 21, 2015 and a release date for all EAP builds is some date in November (when we expect to release R# 10). So, your subscription does not cover such builds. Please renew your subscription and it wll be fixed.
Please file a request here http://resharper-support.jetbrains.com/hc/en-us with a screenshot of the issue.
Thanks!
Please try installing EAP5 build https://confluence.jetbrains.com/display/ReSharper/ReSharper+10+EAP
Same here even after installing EAP 5

Thanks Alexander; installing the new EAP 5 has enabled me to restart the trial.
