When I do this step:
3. Import the product-dbtech_thanks.xml file from the "XML" folder at AdminCP ->
Plugins & Products -> Manage Products -> Add/Import Product
It's modifying the post table, which takes a long time on large forums. Under no circumstances should you stop the page loading or anything, unless you get an error message.
I waited for more than an hour, until it eventually stopped loading. Prior to it stopping, there would always be a status (on the browser) indicating it was transferring something, however after a while of altering the post table the status message disappears and I don't see any status message. I'll try it again.
Edit: It's been an hour and the results are worse than last night, it stops transferring before upgrading to Version 1.0.1.
Issue solved, imported it up to the point where it said Upgrading to Version 1.0.0 and then immediately stopped it and then started the import process again and it resumed from there and continued to work
