I had sent an email about this a few days ago to support, got a reply that same day and nothing since. So I figured I'd post here.
Heres my problem. A few days ago I checked SDC and noticed their was a new version of Windowblinds 5.50 available. I installed it naturally because I figured hey, must be some bug fixes right? WRONG! It turns out that it was labled 5.50 but was really 5.10. So I uninstalled it, 5.10 is useless for me because I am on Vista.
So I check back a few hours later and there is a REAL new beta released, 5.49t - I installed it, after it installs it goes to activate like normal and I get an Error Code 6. I tried this a few times and decided to try it manually. Upon putting in my email and OD Serial I got the error "Activation Limit Reached". I followed up by sending an email to support, the support guy told me to try entering it manually (which already had been done) or try offline activation. So I got the offline activation code, replied telling him that doing manual activation failed and pasted in the offline activation code. Its now been 2 days with no responce.
I checked SDC for the hell of it and that mislabed 5.10 (labeled 5.50) showed itself yet again, I have a screenshot of it here: http://www.osirisgfx.com/astyanax/mislabeled.jpg
This mislabeled 5.10 build disappeared later in the evening yesterday.
