You've done a good job considering that English isn't your first language.
I'm going to play a few games now and spot all the spelling mistakes, then edit them into this post.
1. On the loading screen, spelling errors include Vespene, Geysers, and Control. Grammatically, you missed an "s" on the end of "editors" and "testers".
2. You always write "Terra" instead of "Terran". Even in the forums.
3. On the "build refinery" button, it should say "Each one freezes your income for 25x[X] seconds".
4. On the main panel, it should say "A list of all Ability upgrades", rather than "abilitie".
5. On the terran units list, the marauder's ability list should say "Passive ability: Concussive shells" instead of "Passive ability: concusiv shells".
6. On the terran units list, the reaper's ability should be two words: "movement speed" not "movementspeed". This occurs for many other units too (below).
7. When you build a barracks, the icon should say "spawns 2 marines", instead of "spawns 2 mariens".
8. Similarly, the bunker should say "spawns 1 marauder" instead of "spawns 1 maurarder".
9. Also the engineering bay should say "spawns 2 reapers" instead of "spawns 2 reaper".
10. And the sensor tower is missing the "spawns 1 raven" icon altogether.
11. Moving on to Zerg, the Mutalisk description on the units menu should say "glaive attack" instead of "glave attack".
12. The Overseer is a Detector, not a Detektor.
13. I have no idea what you are trying to say when you call the overlord a "beefe tankblob". I would use the description "Creep spreader", since that's its job.
14. Movementspeed again for the zergling, roach, baneling, overseer and overlord.
15. Zergling ability should be "attack speed: +20%" not "attakspeed: +20%".
16. The nydus network is missing the "spawns 3 overlords" icon, similar to the sensor tower and the raven icon.
17. Moving on to the final race- they are called Protoss, not Protos.
18. The Zealot and Observer again have an ability that increases movement speed, not movementspeed.
19. The Templar Archives is missing the "spawns 1 High Templar" icon.
20. On to the main screen: the "X" next to the "NextSpawningPlayer" should read "Next Spawning Player" when hovered over with the cursor.
21. The middle control coloured indicator says "middle controll" and should be "middle control".
