Hi, I have a website hosted on godaddy it was running 4.9. godaddy did some upgrade caused my website to not work any more. when I started my website it went through upgrade script to DNN 5.5 . I do not see any text anymore on my site. and when I login as host I see the following error:

DotNetNuke.Services.Exceptions.ModuleLoadException: C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\home\1c6f035a\aace87d5\App_Web_htmlmodule.ascx.e83a8a49.rzepsdc_.0.vb(54): error BC32206: The project currently contains references to more than one version of DotNetNuke, a direct reference to version 5.5.0.653 and an indirect reference (through 'DotNetNuke.Modules.Html.HtmlModule') to version 5.5.1.22.

Any idea what is wrong and how to solve this problem? thanks for any help...

Thanks Ken,
Yes I am able to login to the site but every HTML container has the error above. I can add new page and new html module to a container but of course I get the same error. how I can install HTML module and where I can download it from? 
on the site it self the host and admin menu still looks like its DNN 4.9 but the CPanel looks like DNN 5.x . I tried to go to module definition but I have no option of install new module nor I can view installed modules. is there away to install it while the site like this?
Also, will I lose all the Text/HTML content that I had before if I upgrade the HTML module?
sorry for all this questions but I am new to this framework.
any help is greatly appreciated.

Thanks Ken. I will give it a shot and I hope it will work.
