Hi m0cej, I wouldn't worry.
If it was just the starting temp then, based on my experience, I think it will be ok. I have done that as well. I just could not get the temp down. I pitched the yeast anyway and it all worked out ok. In reality it probably only stayed at that temp for a few hours right at the start and as it slowly cooled during the night the yeast started to get to work.
Better to get the yeast going ASAP as it is said the beer is vulnerable to infection at the start.
I found that by the morning it was down to the ideal brewing temp.
BUT - Make sure it remains within the ideal brewing range once it has got going then forget about it for a few weeks. Winelight is spot on. If brewed at too high a temperature it will generate nasty tastes/flavours.
Good luck with it!
