Godaddy version upgrade problem

I'm trying to upgrade on Godaddy from v1.4 to v1.5.  I have followed these instructions exactly and just keep getting the following error when trying to run the install script:

We're sorry, an internal error occurred that prevents the request to complete.

Through the db manager I can connect to my db and the connection string looks good.  Does anyone know why I am not able to run the install script?

make sure you backup every-thing (including database)

Please take a look at this video how to upgrade from 1 version to another, it will help you

Still if you face any problem, let me know

I would check the logs by going to the database and looking at the messages.  When I upgraded on GoDaddy I received that error but it was because I had not yet moved over my theme.

that error message is the store   errorpage.htm  which  is thrown up because you have custom errors set up in your web.config file

go there, comment out the custom errors section and insert the following

        <customErrors mode="Off"/>

upload the web.config file and retry

this will not solve your problem but it will let you see a detailed error message which will bring you closer to solving the issue

once you have solved the issue and the store is running, return the custom errors setting to the way it was (that way your customers will see the custom error screen (which you can edit) rather than the compilation error message.

when your store is running normally, you can view error messages in admin --> system-->log

I've tried both the automatic and manual upgrades from v1.40 to v1.50 on Godaddy with no luck.  I continue to receive and unhandled exception ( System.Data.ProviderBase.FieldNameLookup.GetOrdinal(String fieldName) +4837378).  I investigated the exception through MSN and found that the SQL 2005 server needs to be running SP3 CU4 to resolve a GetOrdinal error when attempting to read an empty table.  I contacted Godaddy and tried to confirm update with no luck.  All they would say is that I have to wait until the validate the program.  Once validated, the v1.50 will be available from their website.  Also, couldn't give me any estimate when v1.50 would be available.  Is anyone else seeing this issue?
