I'm glad that we could find a way to help you drummerboy. I hope other people won't have the same bad experience and I'll do my best to avoid that.

BTW, the upload of the single-file on indievania failed last night... I have to start it over from the beginning. It's using Amazon S3 cloud service : do you know if I can resume an upload when it fails with this service, or if I have to start again everytime ??? This is the very reason why I had uploaded ASA in 12 smaller files on indievania : I just can't send the single big file without trouble.

I haven't used Amazon S3, so what I'm saying is just from Googling information.

Although Amazon S3 seems capable of doing pause and resume, I don't know if it's capable of an automatic pause if it's erroring due to a broken internet connection.

According to this
http://aws.amazon.com/about-aws/whats-new/2010/11/10/Amazon-S3-Introducing-Multipart-Upload/
Amazon S3 has a "multipart upload" that allows you upload a single "object" as a set of parts. You seem to be able to eventually upload the files as parts, but you may already be using this feature.

These instructions
http://docs.aws.amazon.com/AmazonS3/latest/API/mpUploadComplete.html
talk about assembling previously uploaded parts.
It also says "if Complete Multipart Upload fails, applications should be prepared to retry the failed requests" and gives a link to
http://docs.aws.amazon.com/AmazonS3/latest/dev/ErrorBestPractices.html

That page has a link to a forum where you might be able to get tips from the developers of Amazon S3.

How large is the upload?

Thanks Jenny, unfortunately it doesn't seem to resume in my case after the internet connexion fails.

The file is 1GB, which is not THAT big, but it's big when you have internet problems

I'm interested in the option to assemble the already uploaded parts !
If the current upload fails again, I'll try this !

For now, it's 28% of the single file that is uploaded, so I prefer to wait quietely without disturbing my PC and the connexion ^^

Still couldn't upload the single file on indievania (operation fails again and again)
BUT !
The game has just been reviewed on Adventure Gamers and got 4 stars out of 5 !

Way to go, Simon!
