I'm sorry if this has been asked before but I recently downloaded the IOS version of DVD profiler with the intention of running it on my Ipad 2.  Unfortunately,  I was charging my IPOD which was plugged into the USB socket of my computer at the time. 

I unplugged the IPOD from the the computer and plugged my Ipad 2 in. Itunes opened, showing the programme in the apps section.  No matter what I did, I could not get it to install.  In the end, I was so frustrated, I deleted it from Itunes.

Firstly, can anyone establish what I did wrong and secondly, will I have to pay another £5.99 to try again?

Thanks in advance,
Peter

I've done that but still nothing.  Can't even locate it on my Ipad.  Please could I have step by step instructions to get it running? I know I'm a pain, but I just don't know what else to do short of just putting it down to a bad experiance and £5.99 wasted.

Try opening the app store app on your phone. Go to the updates tab. At the top should be something that says 'purchases' or 'purchased items' or something similar. You should be able to locate DVDP there with a cloud symbol next to it. tap the cloud symbol to download the app.
If you are unable to locate the app there, contact iTunes support because then something seems to be wrong with your purchase history.
